Fonts going to glyph before editing

[ELPrepress]

I guess I started this project in ai 2024 and when I open it in 2025 some of the fonts go all whack:

If I click on the type I get the "this was created in an older version of illustrator" warning which is how I realized it was a version problem.  It looks correct in 2024 and does the conversion immediately upon opening, and not when I attempt to edit.  I'm not ever sure of the language to report this as a bug.

Hello @ELPrepress,

I'm sorry to hear about the trouble you're having with your file. Would you mind checking if Illustrator 2025 has the same problem opening all files created on the older version? If not, kindly share a sample file here after uploading it to a file-sharing service, so I can check it with the team.

Looking forward to hearing from you.

It looks like I can create a new file in 2024, create a text box populated with lorem ipsum, and open it in 2025 and have it replicate the issue.  It currently appears to be associated with Josefin Sans Bold as files using other fonts and other fonts in the first file don't seem to be changing.

Hello @ELPrepress,

Thanks for sharing the details. I tried replicating this on my end but could not. Would you mind removing the Josefin Sans font and reinstalling it from Adobe fonts to check if it helps?

Looking forward to hearing from you.
