Hi @Gohil Jay ,

Unfortunately you can't as mentioned in this ticket: https://jira.atlassian.com/browse/CONFSERVER-6008 

I would recommend using a hyphen - instead of a . .
So like this: "ab-xyz" .

Cheers,
Peter

There are characters that are not allowed in label names, '.' is one of them, surprisingly. There is no other workaround than using a replacement character.
