DBCooper and Chris ... THANK YOU SO MUCH!!! And thank you for the video!!! I fixed all you pointed out and a few more things I noticed. Interestingly, before I changed the General Wall Default to Outer (great save for a later problem I'm sure), the wall stopped overlapping. I think it had something to do with the custom countertop or the stile issue. I turned off all countertop and backsplashes on all cabinets and squared off the corner ... thank you for showing me that Chris ... I had done a work-around and it was only so-so. To get the backsplash across the lower cabinets only, I duplicated and reshaped the custom countertop and pushed it into place so that worked. ALSO, IT TURNS OUT, the lower half of the tall cabinet got crooked somehow and that was causing issues with the dimensions as well. My wall is still sticking to the cabinet, pulling it along if I move it, but it's in place and all is well. THANK YOU!!!
