Installed font (Conglomerate Medium) automatically replaced by another font in Premiere Pro (PP)

I have an intermittent issue with an installed font being dropped from PP files. Although currently up to date with v.14.8, PP has presented this problem over many updates during the past couple years. It just happened now (again), and I'd like to understand why this happens and what I can do to stop it!

Conglomerate Medium is the typeface I use for a project that I need to frequently update, but from time to time, this font automatically reverts to something else. When this happens, I confirm that the font is active in my account across the Adobe Creative Cloud. I deactivate and then activate a number of times, until PP finally recognizes the Conglomerate family of fonts. I never sign out of Creative Cloud, and Conglomerate fonts always show as "Active" when I check. Why do that fail to appear as an available font in PP and get dropped? Very frustrating, because a dropped font affects all the views within my project panel and show a typeface that I never selected nor want.

I can't see this as a problem for others in this community, so I seriously suspect operator error. Help!
