I know if the elements in a group don’t have enough space, the element are placed below each other. Although with a textframe, if there is more text than the frame wide is, the textframe expands downwards…
Maybe it’s the same in this case? Maybe you can make your group boundaries a little bit wider so the elements won’t crop or placed under each other?
I don’t know if this is the solution. Check the elements in the group if they’re already ‘free’ enough from the groups’ boundaries… I hope this helps…
My guess is that you have an animation when showing the group. It’s an issue I have had before too. Try a different animation, one that doesn’t resize the popup before showing it.
I just use animations that slide up or bounce in and out instead. I wish they would fix it. I would report it as a bug so they remember it’s still an issue.
