Error message when trying to delete a limiter

[cm216]

Hey guys, maybe someone here can point me in the right direction.  We've got a couple of old limiters in our pfSense 2.2.5 firewall that we want to remove but we are getting an error each time we click the "delete this queue" button:

The following input errors were detected:

This pipe/queue is referenced in filter rules, please remove references from there before deleting.
This pipe/queue is referenced in filter rules, please remove references from there before deleting.
This pipe/queue is referenced in filter rules, please remove references from there before deleting.
This pipe/queue is referenced in filter rules, please remove references from there before deleting.

I'd like to remove these unused limiters before we upgrade the firmware on the unit.

Is anyone able to point me in the right direction on how to resolve this?  There are no firewall rules using this limiter that we can see.  We don't have any queues set up either.  Someone in another thread mentioned something about editing it from an XML file, but I don't know which one nor what portion to remove.

Any info would be great!
Thanks all,
Chris

Just ran into this issue.
When the Limiter is disabled, you will be unable to determine it is actually set on a Rule.
Enable the Limiter, and you'll be able to find it on Rules and remove it.
