I'm running Team City Enterprise 2019.1.5
We've been successfully using GIT VCS Labeling as a feature for months where we add a build label BL_%build.number% to GIT. In it, I have a filter to use the default branch(master) as the filter: +:<default>
Recently I was asked to label any non-master branches as HOT_%build.number%. Easy enough, I add a second VCS Label in the build feature, and set it to -:<default> . This is correct but it's not working. I even used the wizard to write it for me, and arrived at the same -:<default> setup. I've even tried doing -:refs/heads/master. No Dice. No matter what I do, Team City does not label non-master/default branches.
What's wrong with my setup?
