"Save our Ship" 1.0 Stuck

[Jekko]

I'm running 1.0 with the Save our Ship mod. i built a small enclosed ship and successfully added a cryosleep chamber and other elements inside. But then decided to increase the size of the ship. Since doing so, any attempts to add elements w/in the ship bring up the the fault, "Must place inside a fully enclosed ship hull". Screen shot attached. Am I doing something wrong? Will disassembling the parts and building a new ship from scratch serve as a work-around?

Does "fully enclosed" mean roofed too? Because it doesn't look entirely roofed to me.
