Filter has stopped working since update

[Rebecca Kirkby]

Our IT installed some of the recent updates, and since then a filter we have had set up that has worked fine for over a year, has stopped working.

The filter was originally set to this: 

project = BIT AND labels in (Monthly, QM1) AND "Epic Link" = BIT-2068 ORDER BY summary ASC, priority DESC, updated DESC

Now it only works if we remove: AND "Epic Link" = BIT-2068

which doesn't help us at all as we need to limit the filter to tasks that are in that particular epic.  

Has anyone else had any issues with filters since updating their JIRA? Can anyone think of a work around?

Many thanks.

ETA:  I've checked and I can filter other Epics, just not this one.  Not sure if that helps anyone think of an answer?

As other Epics were able to be filtered I have resolved this by creating a new epic, assigning all of the tasks to it, deleting the old epic, and then amending the filters to point to the new epic.  Quite a bit of work but at least it's working!
