New user. Random object artifacts appear in design and unable to remove them. Downloaded the Tiny House template and modified it for my project using Suite 2018. Objects show on floor plan and in 3D rendering. However, I can't select them. Unable to delete. Object include what appears to be counter tops, foundation components, etc. Puzzled. Wondering if the template (Tiny House) was created in Pro originally and I'm using Suite to edit/change. Thanks in advance for your suggestions. I have tried open google search, knowledge base, user forum, FAQ, product help system.
