How to remove extra quorums?

I'm a relatively new membership clerk and the bishop noticed that somehow we have two extra priests quorums. The first quorum has all the usual priests in our ward, the second had unordained priests and the third quorum was empty. I moved the unordained priests into the first quorum but I do not see how to remove the extra quorums in Leader and Clerk Resources nor on MLS.

Has anyone else come across this problem or know the solution?

It isn't intuitive. Go to the first priests quorum and click on the Members tab. There should be a little pencil icon to the right of the quorum name. Click that. There should be an option to combine it with the other quorums. Do that twice and you should be back to a single quorum.

Thank you!
