lol np. thought that’s what I said but ya might be like me I get so focused that I develop tunnel vision and can’t even see the light of day. 
but happy if I was of any help at all. 
but I’m curious though so if you have time, create a new BP (actor) and test this:
add a scene component you’ll find it in the list then add the mesh component, this should allow transforms etc with anything below it.
(in case you want to add several meshes and other components now or later)
then add a mesh component, adding this last should attach it to the scene component that is the root, if not drag it on the scene component (this should make the scene component the root)
(this is where you use the detail panel to add the actual mesh, not the top one - leave the top that refers to the BP (self) alone)
try this and see what you get, not sure how this would work the way you are using it in a construction script but curious to find out
(and don’t forget to make it Static - lol )
all in all, looking better all the time. again good luck n update so we can see how it’s going
