Compile format changes not being accepted

I have duplicated a Scrivener default format (Version: Beta (1078037) 64-bit). I select Compile, choose Compile As, click on Edit Format. I make changes in font, font size, etc after clicking on the “Override text and notes formatting” box in lower left. I save. Nothing ever changes. I’ve tried it with numerous formats, numerous editable Project Formats, and all the Layout Names being offered. I’ve tried it every which way from Sunday. No luck. I’ve watched online videos out the wazoo and I’m pretty darn sure I am doing it right. It is difficult to not think it is user error.

So, compiling in any manner other than the default Project Formats is a fail. Thoughts?
