PNG import issue with InDesign 16.3.1
I'm having an issue with InDesign CC (16.3.1): some PNG files are imported in a green frame instead of being transparent. For example, when I import (whether with the shortcut cmd + d or not) the PNG of an image (1), it appears with a green background, while this same image only with an additional layer (2) appears with a transparent background, as it should. However, it is the same export format with the added layer displayed or hidden.
I would like to point out that this bug only appears when importing into indesign, I don't have this problem when I import the file into Illustrator.
I didn't have this problem before, I downgraded from 16.3.2 to 16.3.1 and still have the same problem!
Thanks in advance for your help!
