Different rules for importing landscape vs resizing

When importing a landscape from a height map the “Number of components” are limited to 32, however, when changing component size the editor allows any calculated number of components to achieve the resize. This means that if I want to import a large landscape (i.e. 2041^2) the editor will only allow this at a 255 section size and the landscape must be resized to achieve anything else, even if not actually resizing (i.e. the LCD of 2041 for 255 and other options is 15). It appears there is height information loss when performing this as well even though the overall resolution does not change.
