My Local BSC network: nodes don't receive any reward for creating block

Question

I built my local bsc network based on the tutorial: https://docs.binance.org/smart-chain/developer/deploy/local.html This network consists of 3 nodes, each of which is run as follows:

./build/bin/geth --identity "node1" --datadir node1 --networkid 332211 --allow-insecure-unlock --nat extip:xxxx --port 30303 --rpc --rpcaddr "xxxx" --rpcport 9545 --rpcapi="debug,eth,net,web3,txpool,parlia" --rpccorsdomain "" --rpcvhosts "" --syncmode 'full' --mine --miner.threads=1 --miner. etherbase="0xxx" --unlock 0xxx --bootnodes "" --password password.txt

Same for the 2 others

I was able to interact with the network normally: transferring funds or deploying smart contracts.

However I don't see the accounts of the nodes that are rewarded with coins every time a block is created.

Please help
