Ship Tailor Bugs

Upon opening the ship tailor, it always resets to the default parts/materials the ship comes with. I end up having to exit and re-open for it to show my ship correctly.

Also, Windows and Materials are getting linked together, again. I have my ship set to Type 4 windows and Type 3 material, but when I re-open the tailor, it keeps defaulting to Type 4 for both.
