Allow subscriber label name onetime

Hello team,
i noticed i can create multiple times label for same name. yes i know it's generating different label id and showing subscriber counts but due to this getting confused during broadcasting so i suggest you to limit label name to onetime and dont create duplicate label name.

Thanks

Okay, I am forwarding this to our developers to put restrictions on creating the same label name.

Thank you.

Let me know once fix

it's done?
