Look dude, I don't want to call you a liar, but there're some significant contradictions in your story. Either you totally flubbed your wallet file and your seed phrase (one or the other okay, but both?) or you forgot some extension word (unlikely since you're seeing transactions in the wallet without an extension) or, the most likely answer; you purchased/found/downloaded this file that was purposefully corrupted to make it look like it has some bitcoin in it.
If you have a private key that restores an address other than one you want restored, then you don't have the right private key. It's that simple. Going around in circles asking the same question worded differently won't change that fact. You're not the first person here insisting he's had an obviously butchered file since it's creation.
I have gone through the whole thread and it took a lot of my time. Thanks to you man for catching the lies of the @OP because otherwise many of the forum members would give their precious time to answer the @OP for helping him out in fixing of that wallet. I have seen many similar posts which were basically created by similar people like @OP to waste the previous time of the members and I think we all should at least be more alert next time because if these type of users continue posting such made up stories and we all give our time to such posts then they would take it for granted. I recommend everyone to avoid such posts when you smell something fishy because we won't be able to help people with such mentality. They will continue to lie like that and will made many more different stories to get our attention and in end they will log out from the account and create another account to post something similar by changing the theme of the story.
