There was an issue where in the backend the entries are sorted case insensitively, but when sorting the entries in viewsproxymodel it was done case sensitive. This caused that albums and other entries in the sidebar that started with a lower capital letter would be pushed to the bottom of the list. This discrepancy made it so you could click an album on the sidebar and the actual album that opened would be completely different that you clicked.
