[opensuse-buildservice] Trying to add ARM architectures to my OBS installation

Hello,

I am trying to add aarch64 and armv7hl to my OBS server. In the web interface, I check the boxes for aarch64 and armv7hl (and also uncheck the one for armv7l, since it was checked for some reason.) However, the changes don't seem to take - when I leave the page and come back, aarch64 and armv7hl are unchecked, and armv7l is still checked. Am I doing this right? I don't see an "update" button anywhere on the page (and the "update" button on the main configuration tab doesn't seem to help.)
