Word now only recognizing the bold font of my Adobe Pro typefaces--Powerpoint and Excel work as expected

Hi all,

I'm hoping someone can help me with a weird thing where two of my Adobe Pro fonts stopped working properly in Word. This is occurring both on my 365 account on my home computer (iMac Pro) and my Office 2019 license (MacBook Pro 13" 2017) on my work computer. Both are running the latest Catalina (10.15.6). I only just noticed the problem in the last few days. So I don't know if it was a recent Microsoft update or what. Everything was working well before I went on vacation at the end of August [edit: I meant end of July].

The two affected typesets are Adobe Garamond Pro and Adobe Caslon Pro. Long story short, the version of Word on my 365 subscription (16.40 20081000) and my Volume License 2019 (16.40 20081000 & and on the most recent prior version of 16.39) both are acting as if I only have Adobe Garamond Pro (and Adobe Caslon Pro) bold on my system. So all my text is now bold. Word is able to see that I have regular, italic, and semibold (as it lists them as part of my fonts), but when I try to manually select regular, italic, or semibold it ignores my request and still shows only bold (with a checkmark next to it indicating that I have selected bold). No matter what I do, it only allows me to select bold for those typefaces. Other typefaces seem to work fine, though I admit I have not tested them all. 

Importantly, this problem does not occur with Powerpoint or Excel. When using those applications, the Adobe typefaces work as expected. Those applications see that I have regular, italic, and semibold and it lets me choose among them. Same when I use the Apple Pages application. Everything works as expected there.

Anywho, Adobe Garamond Pro is my go-to typeface for work, and so now I'm in a pickle. 

I'd appreciate any help you might be able to offer in tracking this problem down.

Best,

Tomas
