Mongos doesn't redistribute the data among shards

Hello there. In our project data is stored in a cluster with two shards each having 3 nodes. Now we’re going to implement access control to this database. Db’s are containerized. The problem with the docker mongos is that they dont have mongod.conf in their /etc/ folder but have mongod.conf.orig. And I couldn’t manage to activate AC by modifying the conf files. So I recreated the cluster again but with AC is on this time. I setup shards and setup a role. Authorization is working as I wanted. I also successfully added shards. But since I recreated the cluster, I inserted the archive dump I got from the unauthorized cluster via mongorestore. The data also had been restored successfully. But all of the data is holed up on the first node of the first shard.

        unique: false,
        balancing: true,
        chunkMetadata: [ { shard: 'shard1rs', nChunks: 1024 } ],
        chunks: [
          'too many chunks to print, use verbose if you want to force print'
        ],
        tags: []
      }
    }
  },

As you can see all of the chunks are in the shard1rs. My question is how do I redistribute these data? Or should I mount the volumes with each data of the nodes?

Any help is much appreciated.
