Summary sorting is messed up

Summary sorting is messed up

I wish this Summary View to be sorted by the first 2 columns.  Simply by editing the title of columns 3 and 4, it sorts by those columns instead and I am unable to remove the sort (without deleting and re-adding columns 3 and 4 - but then the cycle starts all over again as soon as I try to edit the column title).
 
Correction - it isn't the updating the title of the column that is affecting the sorts,  it's switching from Edit Mode to View Mode.  Set my summary up in Edit Mode,  make columns 1 and 2 sortable.  Press View Mode, and it shows sorting by columns 1,3 and 4, and I am unable to Remove Sorting from columns.
