Well every page has to have at least one layer (MobileSheets automatically creates one), so let me ask this - does this mean songs in your library with no annotations now have two layers? You said every song in your library was affected, correct? I'm going to need to figure out what list of steps results in the issue you are seeing. Given that you are using library synchronization and the companion, that increases the number of variables involved, so we will need to try to narrow this down. I synchronize all the time and regularly add songs with the companion, but I've never seen layers created out of nowhere, so I'll keep an eye for this, but without a list of steps to reproduce it, I don't have enough to go on to investigate it. If you can figure out a way to reliably reproduce an issue, please let me know and I'll make sure to get it fixed immediately.

Thanks,
Mike
