browse-at-remote/browse not finding remote github enterprise branches

[mstorus]

Hi,
I'm not able to M-x browse-at-remote/browse successfully on github enterprise branch other than master.
First I ran git config --add browseAtRemote.type "github"
Then I pushed my branch to github enterprise.
Then when I edit a file and try M-x browse-at-remote/browse, I'm shown a prompt that says Select remote branch:

1. I expected browse-at-remote to automatically know the current branch name
2. When I enter my branch name at the Select remote branch: prompt, it opens my browser to a different, unrelated repository on github enterprise, and always on the master branch

Let me know if I can provide additional information.

Thanks
