Attributes Panel shows Overprint for mixed selection
The Attributes panel shows that a selection of multiple objects is set to Overprint when the selection contains objects that are not set to Overprint. Only if a non-overprinting object is selected prior to the group selection, will the Attributes will correctly show the "-" (Dash) to indicate a mixed selection. See Screenshots attached.
I am happy to share that we have fixed this bug in our latest release – 25.3.1 which is available worldwide now.
Going forward, our goal is to fix as many top User-Voice bugs as possible and as frequently as possible. Given the nature of the fixes, some of the bugs will take a longer time to fix, but we are on it.
