Rescan likely did nothing at all. It goes through the blockchain to find transactions that are missing from your wallet. It is only very rarely needed (like when you manually changed things in wallet.dat).

Instructions :

1) Restart Agama, Select dropdown click on "custom" Instead native mode


2)  Click on Activate coin

3)  Select "Komodo coin" on dropdown and select "Daemon Param: rescan"


4)  Click on Activate coin, This will take some time rescan the wallet.
