Changes in a song group does not correctly update the bottom song
When a song is deleted or move away from a song group the last song in the group will no longer point to the right song. The last song entry in the list will instead point to the second last song. This means that if you delete or move one or more songs from the group and then select the last song in the group, the information displayed will not be correctly. The information will be from the second last song and not the last song in the list. This means that all changes to the last song in the list actual will be made to the second last song.

The only way to work around this bug is to refresh the window to refresh the group list (F5 or the menu View/Refresh). Changing away from the song group and back will have the same effect, because the group list also is refreshed in this way.
