Trouble with duplicated layers when importing Illustrator file with multiple artboards into InDesign

[Mattia Rosa]

Hi, I have an Illustrator file with multiple artboards and elements arranged on different layers. When I import the file into InDesign, the layers get multiplied based on the number of artboards, and every time I have to go on a treasure hunt to hide the layers that don’t correspond to the graphics on that specific artboard.
I cannot and do not want to split the artboards into separate files.
How can I fix this in Illustrator and InDesign 2025?

Hi everyone,

Thanks for sharing your updates on this. Could you please confirm the exact versions of Illustrator and InDesign you're currently using? The latest ones are Illustrator 29.8.2 and InDesign 20.5. Are you on these builds? It would also really help if you could share an affected sample file where this duplication happens, so we can test it directly and check with the team.

Looking forward to your update and the file, so we can investigate further.

My programs are up to date, so I’m using the same versions as you mentioned.

The problem is that when I create a new Illustrator file — for example, with 3 artboards and 3 layers — and save it as a .ai file, it shows a total of 9 layers when placed into InDesign.

I noticed that this doesn’t happen when saving the file as a .pdf — in that case, it correctly shows only 3 layers.

This issue didn’t occur in the previous version of Illustrator.

Hi @Ondřej24793640d1mp,

Thanks for confirming the versions and sharing your observations. I tested this on my end by creating a new file in Illustrator and placing it into InDesign, and the layers did not duplicate, everything displayed correctly. This makes me think the issue might be specific to the file or something within its structure. Could you please share an affected sample file, so I can test it directly and check with the team if needed?

Looking forward to your update.

Hi, I’m sending the file. It’s a newly created file in Illustrator. When placing it into InDesign (command + D), it shows 9 layers. The file has 3 artboards and 3 layers. In the past, it correctly displayed 3 layers. The issue appeared after the latest update.

TEST.ai

It shows the following error. 

Correct the highlighted errors and try again.

• The attachment's test.ai content type (application/postscript) does not match its file extension and has been removed.

Abhishek,

as already posted in another thread, here is a very simple Illustrator file for inspection.

https://drive.google.com/file/d/18KXOHa9kYzY7AJ9B294USJ-NmuK_MYiA/view?usp=sharing

It contains 3 artboards and 3 layers. Place it in InDesign while Show Import Options is turned on. In the Import Options dialog go to the Layers tab and see how many layers are listed there.

Do you see 3 layers or 9 layers (duplicates)?

I have the same exactly problem.  culd find a solution so far. already downgraded the indesign version. 
on top of that sometimes the Indeseign change the colors of the Illustrator files. or mess with the masks. 

since last update i am having this issue.

I can also confirm the problem as per the descriptions above (latest versions of InDesign and Illustrator).

Not quite sure if it is an InDesign issue or an Illustrator issue.

By the way, the issue does not occur if you save the Illustrator document to an older format (e.g. Illustrator CC or Illustrator CS6).

This issue started happening for me exactly as others have described here, and using the current InDesign and Illustrator versions available: Illustrator 29.8.2 and InDesign 20.5. In addition, the InDesign will no longer maintain the layers changed to visible/invisible after using the Object Layer Options. This is very disruptive to workflow. I hope a solution comes soon.

Hi @Lea26905664d7vy,

Thanks for sharing your experience and confirming the behavior. We've tried reproducing this issue internally, but haven't been able to so far. To help us investigate further, could you please share an affected sample Illustrator and InDesign file where this duplication and visibility issue occurs? You can upload them to a cloud service like Google Drive or Dropbox and share the link here, or via DM if the files are confidential.

Once we have the files, I'll check them with the product team and update you.

Looking forward to your response.

Maybe these files will come through? Link to Drive

Can you disable "Save in background" in the preferences, save the file again and see if it's still happening?
