Stolen motorcycle has been MOT’d since theft - England

I am at a loss as to what can be done with this.

Yesterday, I decided to search on the Gov website for an old bike of mine that was stolen (12+yrs ago). It popped up saying there was a recall on it for repairs - but strangely, the MOT on it expired nearly 3yrs ago. This would indicate that it’s been registered somewhere and therefore hasn’t flagged anywhere that it’s a stolen vehicle.

I’d love to claim the bike back, despite how long it’s been.

What’s the deal here? What can I do, if anything? I’m surprised it was able to be registered again.
