Everything is in the title 🙂
The bug doesn't occur anymore when renaming the folder without the "\_"
Plateform. MacOS 12.6 (Intel processor)
PS: Thanks for this GREAT software on Mac 😃
Cheers

> Hi Jon and welcome! The issue you're experiencing is due to Mp3tag being a sandboxed application.

It's possible that Mp3tag has already stored a secure bookmark for the folder without the underscore.
