Hi @Gary_Aigen ----- Thank you for the report and my apologies for the troubles. While I understand the current issue is indeed troubling, you can rest assured that all of your edits will be maintained as the application saves that information in your data base.
In order to accurately evaluate what may be causing this issue, may I kindly ask you to please describe, in detail, your current setup as well as your network topology. The more information you can provide about the gear you are using (DACs etc), how it is all communicating (wifi, ethernet, both), and what type of networking hardware you are implementing (routers, repeaters, extenders, powerline adaptors, switches etc), the better 
Thanks!
