"Global CCU Limit " field on "Configuration" tab becomes empty after setting out of bound value for the same field on "Live Mode" tab

How we can reproduce it
--- please see attached video for more info ---
1 Go to the web site https://developer.cloud.unity3d.com/projects/
- you need to have Live Mode enabled for your organization !!!
2 Create new project there and Configure multiplayer
3 Go to "Live Mode" tab and set some out of bound value for the "Global CCU Limit " field
4 Go back to "Configuration" tab

Actual result:
"Global CCU Limit " field on "Configuration" tab is empty and you are allowed to set some very big value to the "Max players per room" field - if you press Save button then it will be saved successfully on the server (what is totally wrong!)
