Can't find adress

Hi all,

About a year ago i fucked around some with metamask to try out uniswap. Got some failed swaps and forgot about it because the amount was not that big at the time. Recently found i could claim the 400 uni airdop which made me look for the adress again. I had a couple mnemonic phrases lying around and checkend them all but no luck. Now there is 1 account where the adress is found in ‘recents’ . The bad news is when i check etherscan nothing moved from that adres to the ‘recents’ adres ever. (Or even show 1 transaction) can someone explain to me how this is possible and if it is worth looking in further.?
Thanks in advance
