Landscape height map issue 5.3

Hello,

Is this a bug or am I doing something wrong? I’m trying to import a height map in to a landscape and I’m following UE documentation to setup landscape’s parameters

I get this result:

It loads only a portion of my height map and landscape regions are very stretched out.

Ok, so I managed to load the whole height map by right-clicking on the layer and loading the height map a second time.
