When my account pledges 1.0098 ICP to the nns neuron account

memo: 16255682412800668452

But it returned me an error when making the claim_or_refresh_neuron_from_account request

Account does not have enough funds to stake a neuron. Please make sure that account has at least 100000000 e8s (was 0 e8s)

when i use the command

dfx ledger balance b9ef8c5cc604e52def45d50e8ca32b3eba53c25c2d03287930525747e0bea126 --network ic

The check found that 1.0098 ICPs have been transferred to nns
why is that
