Using SourceTree 4.2.1 (248) on a 2021 14" MacBook Pro with Apple M1 Pro chip, macOS Monterey 12.6.3...

My workspace has 2 remotes configured: "gitlab" (pointing to our in-house GitLab server) and "devhouse" (pointing to the git server at a development house we're working with).  My current branch was cloned from our local gitlab server - you can see this in the graph view - it shows "my-branch" and "gitlab/my-branch".

When I right-click on the branch name under BRANCHES in the navigation panel, on one of the options is "Push gitlab/my-branch" with is fine.  There's no mention of the "devhouse" remote 

However, when I click the Push button on the toolbar, "devhouse" is offered as the remote name.  This makes no sense - it ought to be offering me the remote that my current branch is tracking, "gitlab" in this case.  Furthermore my current branch is not selected.  It should be.
