CTM Not working?

Following a previous (admittedly old) question's answer, I remade a connected textures pack for stone slabs, after my hard drive was wiped.

The issue arising is that only the bottom and top of the slabs will now connect.

This seems odd to me. The files have been setup 100% the same as the answer instructed, and this used to work. I am using Optifine 1.12.2 D3, which has CTM built in, on forge 1.12.2-14.23.4.2379.
