Glitch that's only affecting me!

Hi. I'm not being a snob, but I can't find anyone else having this problem.

Please don't dismiss this post simply because I mention the game 'Banjo Kazooie'. I'm not actually sure if it's a problem with that game or not. Anyways, for anyone who's familiar with 'Banjo Kazooie', there are secrets that you can unlock at the end of
the game/reaching a certain requirement. These secrets are known as 'Stop N' Swop'. For some reason whenever I start a new game, two of these secrets are unlocked, and all the 'Stop N' Swop' locations are available at the very beginning of the game.

The reason why I'm not sure if this is a problem with the game or not, is because I've started a new game using a different gamertag, and it doesn't happen with that. I've tried everything to fix this glitch. I've uninstalled the game, I've deleted all my
saves while in offline mode. I even changed my gamertag, but nothing works.

I know people will say that I should just delete that gamertag, and start over if it's bothering me so much. The problem is, I actually purchased games with that gamertag, and I have a gamerscore that I'm kind of proud of. It's not huge, but it's not too
bad.

So I'm wondering what anyone thinks, or can figure this problem out. I've reached out to Rare, but so far I've gotten nothing back. Below is a youtube video I made showing what I'm talking about.

Thanks!
