CRL: "Overlap construction is not allowed."

[TK7892[501st]]

Hi everyone, I am working on my armor to be reapproved and I see this phrase pop up in a few places on the ANH Hero/Stunt. I am trying to get basic approval but I am unfamiliar with the term "overlap construction." I'm sorry if this has been asked before but when I searched the forums I saw lots of mentions of overlap but couldn't find an explanation of what it actually is. 

Thanks!

Currently your armor is assembled overlap method.
