Storyline "save as picture" function acting strangely

Since the last SL update, Storyline is doing some odd things when I try to save a group of objects on my slide as a single picture. Sometimes, it just won't save it. But recently this is happening:

I save a certain group of pictures, let's call it group 1. Then, I decide I want to make a few edits to the group, and save that edited group as group_1_edit. But storyline saves the original group 1 instead. This happens even if I give it a completely different name. For some reason, SL is saving older versions. Any advice? Thanks so much. --Daniel
