The fully zoomed out maps created near zero on my switch do not present the coordinates from -1024 to 1024 like usual. They show up from -48 to 2000.

Zero coordinate is therefore in the top left corner, 48 blocks from top or left edge.

This has no effect on spawn point.

The same seeds spawned on PC make me appear on the same set of coordinates as the Switch, but maps work correctly on my account on both PC and mobile.

Please note that as of today I have checked for corrupted data, deleted the game and redownloaded it, deleted all of my save data and the game simultaneously, reinstalled and rechecked for corrupted data, redeleted and reinstalled again, to no avail.
