Reordering Session Groups works inconsistently.
I believe it may have something to do with space trimming/filtering in the "move to position" list selector. That is, it appears to happen when the "above" item selected within "move to position" dialog is one that uses more than one consecutive space in the .
When I remove the sequential spaces (a failed attempt at indentation) I am again able to use "move to position" consistently.
