[Freeswitch-dev] event filter add order

I am noticed that I do not receive the BACKGROUND_JOB event if filter for the given event is added after filter on Unique-ID filter. e.g. if I do filter Unique-ID XXXXX filter Unique-ID YYYY filter Event-Name BACKGROUND_JOB I do not receive the BACKGROUND_JOB event at all but if I do filter Event-Name BACKGROUND_JOB filter Unique-ID XXXXX filter Unique-ID YYYY I receive it Seems a little odd, since described that it's a filter in Is the given intended behavior or a bug?
