Blu-Ray problem

[Villey]

So I ordered a 4K disc of Wall-E on Amazon and it came with a Blu-ray copy with bonus features alongside it. What's weird though is when I put it into the MKV program it recognizes the bonus features or at least one of them, but it doesn't recognize the movie at all and I've tried every method I can think of. I also tried To do it manually but I don't know how and there's no tutorials on how to do it really. So I'm mostly just seeing if people will respond so they can give me their ideas and how I can fix it cuz I would really appreciate any help.

When you put the regular blu-ray in your drive and open it in MakeMKV, what does MakeMKV show?
