ABR 11 Srvr - Remove 2nd location (replication)

I have a backup plan that replicates to an alternate location. I would like to remove the alternate location from the plan and I don't see a way of doing that. Does anyone know if this is possible?
When setting up a backup plan, there is a checkbox that "turns on" the replicate to a 2nd location. After you select it, it no longer shows up in the edit plan options.
Thanks in advance for your help!
