I'm using sourcetree1.8.1 on mac osx10.9.1.
Once I push commits to "forces" branch, and I remove remote branch "forces".
But sourcetree suggests "forces" branch repeatedly.
Is it cache? How can I remove that?
When I commit code with a option "Push commits immediately to: origin", commits are always going to "forces".

But it has only mater branch.

How can I remove "forces" auto selection?
