Still lists Live before LP
You are grouping by virtual tag. The virtual tag outputs: LP and Live, and there are no 'magical' traces of G1, G2 left in that.
Live comes before LP in the alphabet.
Your sorting settings have no have effect on the main grouping itself.
Only on what's inside that grouping.
Sorting also will work for sub-grouping. (which you don't seem to be using)
Perhaps read the earlier suggestions again?
