When I click Merge "Production" into current branch the confirm message is:

"Are you sure you want to merge 'File Status' into your current branch?" (see attachment)

----------------------------------------------------
Merge file status (see attachment):

git -c diff.mnemonicprefix=false -c core.quotepath=false merge "File Status"
merge: File Status - not something we can merge

Completed with errors, see above.
-----------------------------------------------------

Note: Same issues is happening when I try to merge any two branches using the right click "merge xxx into current branch", or try to delete a branch (attachment).

See like the selection on the tree is not working properly and every time it jumps to the top of the tree, that is "File Status".
