Nintendo switch version after this update I went in to work on my house and there was this section where I need to fill in with quartz slabs but when try place it won't attach to adjourn spot of desire it instead will only place at a gap below.

top part is water below is sand both are upper part of a house. Inside house where was slabs were removed when placing the sand blocks now I go back inside house to fix up but won't let me fill gap with quartz slabs if I remove the sand block I can replace with any full size block but not slabs. If I try place full size block it leaves slab size gap. Didn't have this issue before this update
