I'm using a lot of mods, including Connected Living Spaces, which makes this more confusing. I can not remember if vanilla game allowed this internal transfer, though.

Here, I used two CoT Jr. Construction ports because for some reason the docking variant doesn't snap to the node, though the docking variant was remaining green so it was possible to manually center. But, I'm out on the pad and I'm showing that landing can is right side up because the door is supposed to be on the top and the crew cabin has a door on both sides.
P.S. - sorry, idk why the images aren't showing in post.
