Problem with printing to Adobe PDF (fonts)

This is so strange! Yesterday I fixed the font problems (changing 2 fonts that I actually don’t use, but they are still there) in a book. I printed the book with the Adobe PDF-writer. Today I realized that I hade missed a thing I changed yesterday in one of the files, so I fixed it and tried to print a new PDF. But no - the fonts I fixed in all the files yesterday were now back. How can this even be possible? Now I have to change them again!

FrameMaker 2022 (files were previously saved in FrameMaker 7.2)

No where in the files are Helvetica or Times used, but I still get this. The pic below is from a file I changed (and managed to print) yesterday.
