Deleted Branches still appearing in branch selection dropdown

Hello,

I am not sure if I am just missing a step here.  I am using the mac RH 2020.3.36 build.  I use git (bitbucket) for versioning control.  After deleting my merged branches on bitbucket, I am still seeing them as available branches when i go to Collaborate > Switch Branches.  I have tried the refresh button, Status Refresh, and closing/opening the app. 

Is there some profile file that i need to edit to remove these deleted branches from the dropdown?
