" zoom in 2 times "

*What I expected to happen was zoom in at location im standing. but not zoom in corner of the map again i expected zoom in different location so i try again go to other location and try again it craft the map with shear it keep zoom in same location in corner of the map it won't zoom in other location that i want it to be but it show same corner of the map but i want different location

*What actually happened was it zoom in other location. so i try again it keep zoom in same corner of map location in the map then i try again walk far away from snow biomes location that in the corner of map so i craft map with shears again zoom in second time it still show same snow biomes location that in the corner of the map but i expected it will show differnet location away from that corner of that map
