Open PDF in InDesign not properly working when a vector image is present (.ai or .eps)
When we export a PDF from InDesign with the box "Preserve InDesign Editing Capabilities" checked, if we open the resulting PDF in InDesign, it is perfect, styles are preserved, guidelines, tables, Layers, Parent Pages... All is ok. (just as if a idml was included in the PDF)
However, as soon as we include a .ai or .eps anywhere in the InDesign file, the exported PDF can no longer be imported back in InDesign with all format. Styles are lost or are named "Paragraph1", "Paragraph2", no more guidelines, no more Parent Pages, tables are not like before...
We're trying again every time a new version of InDesign is out. This morning, it was InDesign 21.6 (Windows). Still the same problem.
