Not an Instance of a Logical Switch

Having an issue with SCVMM. It appears someone was able to delete Logical Switches out of the Fabric even though they were in use - either that or SCVMM lost them. I have re-created the switches the Hyper V hosts have configured (they still existed in Hyper V Manager) however I am having some strange issues.

In Fabric I am getting the error "Not an Instance of a Logical Switch" for the ones I re-created. Think I need to clear this error, which will resolve the other problems.

Any ideas?

    @Adam Hutcheson , For the logical switch, Host depends on it. Before removing it, the host need to be removed from VMM. For the deletion, maybe you can check if there's other user has permission did this.

    From your description, I notice we get error when re-create the logical switch. Here, we suggest to remove the old logical switch on Virtual Switches under the Hyper-V host's properties in VMM and then try to recreate again to see if it is working.
