Landscape proxies keep moving to same location as parent Landscape

When loading my World Partition or Cooking the game, I get the following logs:

When seeing their position in the editor, they are all at the same location as the parent landscape. Here is a print of the details of the parent landscape:

And here is a print of the landscape proxies:

When I open the game or load the World Partition in the editor, all of the landscapes are clumped together. I have tried exporting the height map and recreating the landscape, but it gives me a 253x253 resolution heightmap, which is too small for the current size of the map. How can I fix this?
