Remove Build Artifacts is not working

I tried to delete artifacts for a build and noticed that it is not working. I tested this on both 4.4.0 and 4.4.4. If I click on the Default Job, I am able to successfully delete the artifact with the "Remove Job Artifact" Button but the "Remove Artifacts" button at the build level doesn't do any thing. It doesn't remove the artifact from Bamboo or from the stored location on disk.

Attached screenshots are showing the process (Follow the 1 to 5 numbers for the right order)
