The automatic build labeling doesn't appear to be working. For each job in my plan, I label it via [the job] > Miscellaneous tab (see screenshot). Based on the documentation, I should be able to label ALL builds if I simply leave the "Regex Pattern" field blank. Once the build completes however, the build results page doesn't show any labels being applied to the build (see other screenshot). Below is the Bamboo Version I am running. If that field doesn't work the way I'm expecting it to work (i.e. it functions as designed), please inform me what I'm doing wrong.

I'm following the documentation found here:
