map are bug

(before I begin, I would say that I don't found any issue who speak about this, please, if there are can you send me to them)

the map in my world are bug:

1-they show under some of my construction(watch pictures)

2-when I open a map in another part of my world, the map shows me a part of another part of another map:

-I open the map 1

-I put it papers to have ''scale 3/4'' (scale of a Xbox One Edition's map)

-I have now my map 1 with all my construction

-but when I open my map 2 and I put it to the scale 3/4, we see a lot of a part of the map 1.

(I retry yesterday with 1.4 and it's the same)
