Cannot save song with an underscore in it's name

You can add the “_” to a song and it looks like you saved it and return back the loop studio from the song editor.

But the song was not saved and the saved icon is no disabled. Clicking the save icon does nothing.

Removing the underscore allows the changes to be saved.

Hey there, this is not happening on the tested version, will let dev team know anyways, maybe they fixed it
