Font styles from same family replacing each other when installing? (Franklin Gothic Std)

Hi all,

I have two styles from the Franklin Gothic Std family:

• Linotype - FranklinGothicStd-ExtraCond.otd
• Linotype - FranklinGothicStd-Roman.otd

When I attempt to install them they overwrite one another and are flagged as duplicates, meaning I can only use one at a time. How can I install them as a family? I used to have them both installed without issue, not sure if an update has changed things. 

I'm on Mac OS Ventura 13.1

Thanks in advance
