remove a node from the cluster from the structure shown in the image


I´ve been searching for a while and can not find the solution to this, I really apreciate some help.

I am getting and replication error because the virtual machines are searching for a disconnected node.  The error is "The transfer failed: 'Algunos nodos de clúster Hyper-V no están protegidos. Proteja los nodos desprotegidos: 'PlazaLibertad''

So, I think the solution is to erase the node in Rapid recovery (Is actually removed from the infrastructure), but I can not find the way of doing it.
