It seems it doesn't matter if you uncheck Use default display mode for song in Page Scaling Mode, it still uses default settings regardless what you set in song settings. Also it doesn't remmember if Use default... is checked or not, if you open same song again, it's always unchecked.

Also if I try Apply to... button. it crashes the app. You can try it Mike with Abba Medley song from my backup if other songs don't show same behaviour.
