Reproduction:

create a steel monotile and a dark monotile with a stack of durasteel
ctrl-click and change the dark monotile into a steel monotile
they don't stack

this is because material stack code works on paths, and ctrl-clicking a tile doesn't change the path
this also means when you remove one or many tiles from the stack, you get whatever it was originally
