@00pixelparty I am sorry for such a late answer, and possible necroing too; but the AHQ notification mail of you tagging me/posting here, was sent to an odd category in my mail, which I only randomly looked through today. I found a bug report on your issue though, that was fixed november, in patch 1.58.63:
https://answers.ea.com/t5/Bug-Reports/FIXED-Adding-Moving-Deleting-Walls-and-Wall-Patterns-Removes/td-p/6431454
If it matches your issue, and you still have it, update your game. Otherwise post again (I know..) I will look through the trash mail for the notifications from now on.
