Minecraft: Player position on treasure map does not appear?

I'm playing Minecraft and found a treasure map. But on the map the position of the players (small white dot) is not visible. Not in a corner, not tiny. Have already found some treasure map, because it was quite normal. But on this map the player position is nowhere indicated. Restart brings nothing…

Maybe you are outside the area marked on the map.

Oh, but then there should be a dot in the corner. Even if I was still so far away.

No?

So on all maps and on all images on the Internet it is like that. The closer you get to the area, the bigger the point gets. But there's always a point there.

That of the described problem I know of Minecraftservern… If there's not a map of the same world no point is displayed.

If this happened to you but in SinglePlayer I have no explanation for it…

For me, the point disappears sometime, if you go far enough away.
