administrativeMonitor/abortedBuilds - WRONG

There seems to be no way to clear this information. Our Jenkins has been reporting that two builds were "aborted" even though they are months and months old, and Jenkins has been restarted many times since.

Also, I notice a job shows up as "aborted" even though it successfully completed. It subsequently disappeared from the list.

Any idea how to A> either turn this feature off since it is mostly wrong, and/or B> Acknowledge and remove aborted builds?

Note: One of the Freestyle jobs has an "Abort if stuck" plugin but the job completed before it expired. The other has an "abort if stuck" which did fire, but again, that was on March 28th and this is now June 16th.

We are using Jenkins 2.46
