Can’t recover wallet with 12 word phrase

Hello, I need help

I mined 1000 RVN about a year ago and I was trying to recover my wallet. I downloaded Raven Core again and typed my 12 word phrase that I had written down. After a few hours of syncing, my balance was 0 instead of 1000. Tried syncing again, with no luck.

Then I typed the address to which I was mining into a block explorer, and there it said that my balance is 1063 RVN with 107 transactions.

Am I missing something? How can I get the 1063 RVN into my wallet back? I formatted my PC which means I don't have the wallet.dat file, but I thought the 12 word phrase was enough to do it.

Thanks in advance
