I have my private key, and i have my mneumonic key phrase, but can’t seem to figure out what is attached to what….

I made a key, used it a LOT, and then I accidentally got phished, and all the money and NFTs were taken.
Fast forward to now, I have some "private keys" including the one to the wallet that was compromised. I have no phrases for these keys, and I can see I created them in Metamask, so they MUST be tied to the compromised key, right?

Then why when I import the key for the messed up wallet to the NEW wallet I JUST MADE it still imports the bad wallet? Are my other wallets safe? They do not come up with seed phrase, I had to use private keys to backup accounts 2-5 so I am fairly certain THOSE addresses are safe, despite the seed phrase not existing, and possibly being made under a bad account?

Hopefully someone knows?
