Wrong Material from Chosen Material

So a problem I had pop up which was weird was I used wood for the entire building except for the roof, but when the Hearthlings(?) started building it, they were using stone for some walls, and i tried to fix but pausing building and changing several times, and it let me change that front material to wood, but not the back wall or divider or the far right wall. Another thing is the other walls that didn’t change were shown as wooden walls and columns for the description text.

Would show second image but can’t add to post as new poster.

Second Image that shows it says it’s a wood wall but looks stone and also using stone to build.
