It's amazing for delegation

1、Before I delegat the coin to the validator, I query the validator’s delegations, as following
alidator
Operator Address: cosmosvaloper1ks2af3d4q4ugh0e2cfrqpeh0cyhyadyzgsmx9x
Validator Consensus Pubkey: cosmosvalconspub1zcjduepqcmf8vvwzah5shlj58sajf28zeewnm9v0w0s40f7adrqv4ypn92hsd46yq6
Jailed: true
Status: Unbonded
Tokens: 19800000
Delegator Shares: 20000000.000000000000000000
Description: {bcv3 }
Unbonding Height: 51271
Unbonding Completion Time: 2019-07-29 03:20:11.332528243 +0000 UTC
Minimum Self Delegation: 1
Commission: rate: 0.100000000000000000, maxRate: 0.200000000000000000, maxChangeRate: 0.010000000000000000, updateTime: 2019-07-24 09:12:05.356696874 +0000 UTC
2、Then I send a stroke delegation, the command is
./gaiacli tx staking delegate cosmosvaloper1ks2af3d4q4ugh0e2cfrqpeh0cyhyadyzgsmx9x 1200000bcv --from cosmos1kle46uuxm700p40m8w3az6fgumf7qy8c5xzulz --fees=“20bcvs”

----NewTxBuilderFromCLI–txbldr–{txEncoder: keybase:{name:keys dir:/home/ubuntu/.gaiacli/keys} accountNumber:0 sequence:0 gas:200000 gasAdjustment:1 simulateAndExecute:false chainID:test memo: fees:[{Denom:bcvs Amount:{i:0xc000b01940}}] gasPrices:[]}{“chain_id”:“test”,“account_number”:“6”,“sequence”:“0”,“fee”:{“amount”:[{“denom”:“bcvs”,“amount”:“20”}],“gas”:“200000”},“msgs”:[{“type”:“cosmos-sdk/MsgDelegate”,“value”:{“delegator_address”:“cosmos1kle46uuxm700p40m8w3az6fgumf7qy8c5xzulz”,“validator_address”:“cosmosvaloper1ks2af3d4q4ugh0e2cfrqpeh0cyhyadyzgsmx9x”,“amount”:{“denom”:“bcv”,“amount”:“1200000”}}}],“memo”:""}
3、After the delegation success, I query the validator delegation
Validator

4、I want to know what happend

The validator’s Tokens and Delegator Shares is different, so the delegation amount is not accurate
