1- InDesign(17.0.1)

2- When importing this PDF file "Socredo.pdf" in an InDesign(17.0.1) magazine layout, then exporting it again in PDF, the upper background tatoo drawing disappears. This stays true even when trying different PDF export preferences.

3- The expected result would be to have the 2 pdfs identical visually

4- The file "105 Ecopol 2021-2022 Secteurs.pdf" is the actual result, with the missing upper tatoo background.
