checkcommitreadiness return always false for approvals

Hi there,
I'm trying to setup chaincode on fabric 2.2, but, I dont'know why, approvals are always setted to false when I run `peer lifecycle chaincode checkcommitreadiness`:

this is my approveformyorg:
```
peer lifecycle chaincode approveformyorg -o orderer.example.com:7050 --cafile $ORDERER_CA --channelID mychannel --name newc --version 1.0 --init-required --package-id $CONTRACTS_PACKAGE_ID --sequence 1 --signature-policy 'OR("Org1MSP.peer", "Org2MSP.peer")' --collections-config /opt/gopath/src/github.com/chaincode/collections/collections_config.json
```

and its output:
```
txid [376e4c1d55d4cffa08e4d6f3f9032ae21f54e6fd78f8ac1e406037988143b4a9] committed with status (VALID) at peer0.contracts.example.com:7051
```

this is my checkcommitreadiness:
```
peer lifecycle chaincode checkcommitreadiness -o orderer.example.com:7050 --cafile $ORDERER_CA --channelID mychannel --name newc --version 1.0 --init-required --sequence 1 --output json --signature-policy 'OR("Org1MSP.peer", "Org2MSP.peer")' --collections-config /opt/gopath/src/github.com/chaincode/collections/collections_config.json
```

when I run the above command the output is always:
```
{
"approvals": {
"Org2MSP": false,
"Customer": false,
"Org1MSP": false
}
}
```

why?

Any suggestion is welcome. Thanks in advance
