How to activate barman_slot in PostgreSQL?

I am using PostgreSQL cluster with Barman backup tools. I just recovered one of my backups. After recover, I found barman slot is inactive. Later, I deleted that inactive barman slot and created another barman slot. Below is the command: barman cron barman check pg It shows barman not initialized. Then, I ran another command: barman receiver-wal --reset pg It shows receive wal position ahead of current WAL. So, in that case what is the solution? Thanks In Advance for your support.
