I just wanted to pop on and say 'thank you'. I was in the process of sending a 24 page pdf to a client and all the bold of FS Albert font was absolute gobbledygook. I am am on a Mac. I cleared the duplicates as suggested and this solved my immediate problem. I noticed however that I had also duplicate versions of FS Albert Light and this wasn't affecting the typography. For the record the bold that was affected was black on a tint background
If it's a matter of a few footnotes in a document your suggestion will work.
If you have a lot of them you need an automated way of dealing with them.
