Issue moving firewall to firewall group in Sophos Central

We moved a firewall into a firewall group in Sophos Central and upon synchronizing it will give the following Error:

Firewall Transaction Details
ID : 1 | STATUS: FAILED | EVENT : UPDATE
AD server \"{srvname}\" could not be updated
Error:: servertype type MisMatch (500)
{
  "response": {
    "Entity": "adsserver",
    "statusmessage": "Error:: servertype type MisMatch",
    "Event": "UPDATE",
    "status": "500"
  },
  "msg_ids": "AD server \\\"{srvname}\\\" could not be updated"
}

I suppose this might have to do with the Active Directory server already configured prior to moving the firewall to the group and not being able to rename this currently configured AD server. It seems like this is the only issue, underneath (under Show more there are 600+ additional items which do seem to have migrated).

Is that assumption correct?

Is it safe to just hit "Skip (Ignore this failure)"?
