Reimport Tiled Landscape Weightmaps

For some reason the “Reimport Tiled Landscape” -> “Weightmaps” options are not working (nothing happens), neither the “All Weightmaps” or clicking the individual ones. The heightmaps are able to be updated.

I imported my landscape from World Creator 2.0.

UPDATE: Never figured out how to do this, have to re-import everything when there is a change, if anyone figures this out or it is fixed post 4.23 please let me know.

Are they RAW files? Are they in the same location?

I would probably just delete and start over.
