If possible, please create a library backup under Settings->Backup and Restore->Backup Library, upload that to the cloud (Dropbox, Google Drive, OneDrive, etc) and share a link with mike@zubersoft.com. It sounds like something has gone seriously wrong in the database for those songs. If you are selecting properties for one layer and it's affecting multiple, that makes it sound like there are duplicate layers present in the songs, but I'm not sure how that's possible. No other user has reported this, so I believe it's an isolated issue, but I don't know how it got into that state on your device. I'll have to see if there is some code I can add to repair a library that has duplicate layers. I'll know more once I have a copy of your library to investigate this.

Thanks,
Mike
