Date of Last Action Event Monitor

There seems to be a bug pertaining to the date of the last action field. For example, if I create an event monitor where I want to find all events where the “Follow-up Request” action was the last action taken, it works correctly. But, if I indicate that I’d like to find events where that action was taken, say, at least 5 days ago or more, the date filter doesn’t apply. In fact, it’ll still show events where the action was taken the same day that I am running the query. 

I’ve tried looking in the release notes but I can’t find any mention of this bug. My organization is running on assyst 11.2.3.
