I have come across a bug in OpenSong, where if you have a number of items in a set, and you modify one of the items (for example a custom slide) and then you click the "Move up" or "Move down" button, a popup dialogue box asks if you want to save the changes - if you click "Yes", it saves the changes, but also overrides the contents of the adjacent set item duplicating what was just moved.
If the item being moved is a song that has been modified (custom presentation order) and it is next to a custom slide, doing the same actions overrides the contents of the custom slide with the song lyrics.

Thank you for reporting, and thank you for the good description, which allowed me to easily reproduce the issue.
I have prepared a fix for this bug.
