Imported file with a duplicated layer inside

unfortunately, issue still occurs in latest Illustrator version 30.0

I'm experiencing the same issue — when I import an Illustrator file into After Effects, the layers get duplicated. However, the duplicated layers are empty.

@nishu_kush ,thats not entirely true. The further testing I did shows that the issue is not contained to the HDV/HDTV1080 preset, rather, and as also shown by @bookieaka, the issue also presented when using the Web Large preset but with two artboards, rather than the single one pre configured in the template. This would imply that any preset using more than one artboard would also present the issue. 

Hello,

When I import .ai file to After Effetcs In folder with .ai layers, layers are duplicated. I use 2024 and 2025 version and I have the same problem in both versions. Alse, when I changed something in Illustrator file, layers in After Effects are empty. What should I do?

Changing thread status to Investigating.

Best,

Nishu

I still have this issue in AI 29.8.2 update, I found the number of duplicated layers in AE are depending on number of artboard in AI. With default HDTV template has 2 artboards (I tried more artboards = more duplicate layres), if I delete 1 there're not duplicate issue importing to AE but I have to choose to delete smaller artboard to retain all artworks or delete bigger artboard to keep composition size but artwork beyond artboard had been cut off.
