When you click the header to reverse the order, the triangle flips and the list remains in the same (now correct) Z-A order.
Pressing again, the triangle again faces downward, and the list is finally placed in correct A-Z order.
Pressing the refresh button returns it to its previous erroneous state.
This behavior doesn't happen to the list on the Install Tab. Just something weird I noticed waiting for mod updates after 0.18
