I'm trying to change the default exterior wall materials, but whenever I select the walls and choose the default material, it keeps reverting back to a blue siding instead of the one I have set. I'll show you the steps I've taken and the issue I'm facing. If you have any suggestions or solutions, please let me know in the comments.
