My Brave tokens are missing and the backup file isn't being taken input. Its giving an error. Please help

I stored my 24 words key, but now I need to recovery into another computer but when i enter into “brave rewards” icon → “manage your wallet” (gear icon) → Restore
and paste my 24 words, the system came back with message:
“Please re-enter keys or try different keys.”

I don’t have different keys… just those 24 that I saved when I create the reward wallet.

What am i doing wrong?
