Help! Weird Behavior: Infinite Bills & when making an Airlock

[Quantum Jim]

Please help me! So I am not sure what I'm doing wrong. I am very new to modding and 3d modeling, so I tried some tests. I'm trying to make a simple airlock for a manned laboratory. However, I couldn't get Kerbals to exit the lab once they entered (the dreaded "hatch is obstructed" error). So I tried something simpler, and I got a weird bug:

Infinite Bills coming out of the airlock. The Kerbals stay unresponsive, and their lights are always on. I'm not using any other mods at this point either. I'm not sure what I'm doing wrong. Here's what my unity environment looks like:

Could someone show me what I'm doing wrong?

I got it working.... not sure how though. I created a simple capsule, added the airlock, made it in unity, and it worked. go figure...
