Tilemap Matter example not working

These examples are not working currently. Anyone have an idea as to why?

(I will also look into it further and see if I find anything helpful).

Thanks pals.

They work if you switch it to the Dev build. Looks like they are bugs in 3.15.1 that are fixed in 3.16.
