Supernet/Subnet edit doesn't work

Supernet/Subnet edit doesn't work

Hi experts,
I'm trying to assign Supernet/Subnet name and descriptions. But nothing changed when I saved this. Supernet/Subnet name fields still empty
I tried to uncheck box "To get the device details using SNMP", but looks like it also doesn't work, bcs when I open Edit menu again, this option still selected.
Could you please advise on how to fix this issue?
