Fonts Change When Editing Text

[Sunburst Stephen]

We have one computer at our workplace which is being stubborn about fonts but only in certain files. For example we have a text object using the font "Horsham-Bold" (A TTF font). On most of our computers we can edit this text easily, but on one particular computer when we try typing to add more letters to this text, the new letters appear using the font "Adelle-Heavy" (an OTF font) which is a font used elsewhere in the file. We can correct this by reselecting the new text and changing it back to Horsham-Bold, but pressing enter to create a new line reverts it back to Adelle-Heavy.

Another odd thing is that the only computer having this problem is also the computer that created the file in the first place. 

I've looked at some similar discussions on this site, but those cases all seem to involve Postscript 1 fonts, which it doesn't look like we use, and they report the font changing to Myriad Pro rather than changing to another font used elsewhere in the file. Though in another instance of the problem we're experiencing, some Myriad Pro Regular text kept randomly changing to Myriad Pro Semibold.

When I check the "About Illustrator" it says that we're on Illustrator 29.1 for the problem computer, and 29.0 for the computers that aren't experiencing the issue.

Just as others have said... THANK YOU!
I was only experiencing this periodically and only with a couple of fonts but your suggestion seems to have solved the problem.
