When you place the kitchen cabinet in a corner section, it will display an x-ray like effect. this doesn't happen with all of the variants, but if you place different variants of the cabinets next to eachother in a corner shape, it also occurs. This happened to me on the forge version and the fabric version.

Yeah this is a bug that's known to be on 1.1, I forgot to tag the stone variants of the counters and cabinets as not solid/full blocks which causes the issue, thanks for the report, I hadn't noticed it on the cabinets before
