Fonts and Buttons from Assets slides don't transfer from Assets in New Adobe Captivate

I'm moderately well-versed in Adobe Captivate Classic, but I went through the New Adobe Captivate certification course and want to create a new project. I'm trying to use some of the Asset deck slides as a template for slides. It doesn't seem to matter which asset deck I use. 

On the thumbnail, fonts and colors of buttons are correct. However, when I download the asset slide(s) to my deck, the fonts are replaced, colors of fonts and buttons are changed. It's a mess, and looks awful. If I just put one slide from assets in a brand new project, save, close, and re-open, a popup asking about missing fonts appears when I re-open. Is it something I'm doing? Should I change a setting of some sort?  What am I missing here? How do I get the pre-made slides to appear as they seem in the Assets panel without having to recreate them myself?

Currently using version 12.3.0.12.
