"Issues for <module>" block intermittently reverts to tracking drupal core.

Issue Summary

On my dashboard I have 4 "Issues for " blocks. (Views, Panels, Ctools, Contextual Administration in case someone wants to replicate exactly). In the process of adding these, one of the existing blocks would occasionally change back to tracking drupal core when adding a new block. I had instances where it worked properly, and instances where it did not, so the bug seems intermittent. (or it's only happening as the block number becomes even, seemed to happen on the 2nd and 4th blocks but not the third, don't know if this was just coincidence.
