The trend graphs have a number of annotations on them. The change points match a range of commits and cover commits that haven't run. The BF annotations appear to only show up if the exact commit has run. Often we have isolated the commit on one variant, but labelled all variants. The system is smart enough to no longer show the change point, but does not show the BF ticket on the trend graph in this case. For example, see here, which should have a BF on Nov 28th for BF-11411 and a second mark for the fix on Dec 4th. You can see the same BF properly labeled here.
