Font library detached for people with edit access


Encountering this weird problem where people with edit access to the file can not see the font style that is implemented on a design from our published font library, while people view only access can. I have tried giving and revoking edit access to multiple accounts and the result is always the same, while account with view only access can see the font style as named and established in the library, as soon as they are given edit access the font detaches from the library.

For refrence:
Accounts with edit access

I can’t upload more than one image, but for accounts without edit access the font shows as ‘Tablet/Body1/Regular’, as per the naming convention it was saved as.

Any ideas as to what the problem might be? Thanks in advance!
