I have problem on creating a wallet, when im creating a wallet it says it is already exists but when i balance it it says i need to create a wallet. What's the problem?

paola@LAPTOP-OSIKATASVWL:~/resma-medical-clinic/src$ dfx identity deploy-wallet 74t2q-oyaaa-aaaao-qjv5a-cai --network ic
WARN: The default identity is not stored securely. Do not use it to control a lot of cycles/ICP. Create a new identity with dfx identity new and use it in mainnet-facing commands with the --identity flag

Error: The wallet canister “74t2q-oyaaa-aaaao-qjv5a-cai” already exists for user “default” on “ic” network.

To get out of the inconsistent state, please delete ~/.config/dfx/identity/default/wallets.json and try to redeploy the wallet. You can also have a look over here where someone ran into the same issue.
