Doors and Turbo Lifts

[IAMGOOGLE]

I've been playing around with the ship designer and have just noticed that all the doors I've been creating with the door jig are showing up as turbo lift doors, this then creates a bunch of errors about missing stops when I go to finalise the design.

How do you create normal doors rather than turbo lift doors when using the door jig and is there anyway to convert a turbo lift door back to a normal door?

Thanks,
