Apologies for not mentioning that the sites were under controller management and not standalone.  Each site is being managed by a 5.13.22 linux controller in a Docker container (running on various platforms, not that it matters).  I didn't mention it initially as it was only the ER707 firmware that produced change, regardless, I have provided screen shots of my controller setups for the server and clients after getting the 'Cannot Recreate' note from the dev team.  Looking forward to hearing back.
