Export For Screens 4 of 6 Artboards blank?

[FlexAce]

It used to work as expected.

If I do the full document or select artboards, the first four are blank
I tried re-booting the machine and saving the document with a different name
Still fails

Note: Just updated to the latest version yesterday

[Monika Gause]

so the document opens like this? or does it get deleted while working?

[FlexAce]

The document is fine.
The first 4 artboards do not display in the Export for screens
And if I print, files for the missing artboards are created in the proper shape but with no contents.

Are the artboard contents on separate layers?

[Monika Gause]

Can you check if the layers are set to non-printing?

Please show us the layers panel

[FlexAce]

Yes each is on a separate layer

[FlexAce]

They are all set to print

[FlexAce · Accepted solution]

Each layer is a link to a smaller file.
I checked the links panel, and everything looks fine there.
After deleting the links that would not print and then doing another place, the export for screens now works as expected
I made no changes to those link files, so this most likely is something from the update I did yesterday.
Thanks for helping me work it through.
