Rules around Deleting Templates from Slide Master
Hi, I'm self-taught in AS2 and have some questions around the use of templates and how to delete them from the Slide Master. I currently have 3 of the same set of layouts within my Slide Master, rookie mistake, I know.
But I'm needing to retro-insert a module progress bar into my module and want to insert it on as few layouts as possible to minimize programming time. However, when I try to delete some of the extra slide masters, I see this (attached).
What are the rules around deleting slide masters? What impacts when you can and can't?
Thanks in advance for your help and expertise!
