Status in Project Group Summary Page inconsistent with Build Results

After Continuum is working a while the status in the
Project Group Summary Page
becomes inconsistent to the one in the
Build Result Page.

Sometimes the Group Summary shows "failed" but last build was sucessful or last build had never been executed (as in the attached example for eai-base-deploy-helper).

Sometimes the Group Summary shows "in progress" but there is no build in progress.
(A try to cancel says "Project is not in Build Queue", a try to Build says "Project is already in Build Queue").

Workaround: Restart Continuum and Status is consistent.
