This Is More Of A Bug Report Than Tech Support Request.

[Pilotic]

I discovered a bug on my station in Kerbin orbit. With the science lab parts, when you EVA a Kerbal out of one of the hatches, it comes out facing the wrong way before quickly flipping around to grab the ladder in the correct orientation, causing quite significant oscillation. Video is attached.

Yeah, that does indeed happen.  Unfortunately, development on KSP1 has ended, so it is unlikely bugs will be addressed.  If you'd like to submit to the bug tracker, I believe it's here:  bugs.kerbalspaceprogram.com.

Honestly, that's probably not a game-breaking but, and I doubt it will be addressed.  I do not know of a workaround or fix for that issue.  Perhaps try turning off SAS before EVAing a Kerbal.  Good luck, and again, welcome to the forums!
