Local Files don't play. Removed ones still show up

[paskoww]

Hi,

I tried adding new local files today, they do show up in "Local Files" but when I press play I get the message "This song is not available. If you have the file on your computer you can import it."

Additionally some files I unchecked in the settings for Local Files, still show up in spotify and can't be removed.

I tried unchecking<-> checking, restarting spotify and my PC. Any other tips ?

Thanks!
