JP1 Remotes

using an ATLAS 1056 B03 remote
Top menu....Remote....Download from remote.....Downloading
In General.....device buttons 8 devices shows up with setup codes
so far all good, right.....
However, I highlight any devices......Edit Device button not working !
I selected Devices tab.....nothing listed there !?
Only option available there is at the bottom : New

Is this normal ?
Why Edit not available for remotes original devices ?
Why original devices are not in Devices tab ?

Thanks

The Edit option in the Devices tab allows you to edit any upgrades that you have added, it doesn't allow you to edit built-in codes.
