My file seems to run slow when I go to my "Master View" and it might have something to do with 10+ sets of Master slides.
I'm having trouble deleting master slides in my project. I imported slides from a project from last week and it duplicated the same master slides. I now have 10+ and I have made sure they are all using one set of master slides.
I cannot delete any of the ones that say the slides are "used by no slides"
The preserve button is locked and looks highlighted with the text dimmed.
When I right-click any of the unused master slides, it has "delete" and "preserve" text dimmed.
