Minecraft treasure map found Location is marked with an X on the treasure map?

I have just found a treasure map in a box where gold emerald and diamond were also included and the x is just where I found the box, so at the location and now I ask myself why because actually the x should be somewhere else so that I can get it find treasure or not?

That's a minor bug. Although that could also happen in real life 🤔

But I don't know what to do now where is the treasure?

You have to find a new card.
