The way it works is they are originally installed with the small pin telescoped outwards. Once the pin pushes in, I do not think it is designed to push back out again. It's sort of like a one-way ratchet system I gather. As the weatherstripping compresses that pin pushes in more.

I had one that was pushed all the way in and when I adjusted my door it was not contacting the door jam anymore and I could not pull it out. The new one had the small pin pushed out. They recommend closing the door slowly for the first time. That way the pin does not get smacked in prematurely. It sets in one position and then as the weatherstripping compresses over the years it's slowly pushes in to compensate.

when I was trying to pull my pin out, I did read that others have successfully pulled her there pin out. I was unable to pull my pin out.

some people install a small round rubber pad, similar to the ones you would find on the bottom of a chair leg or the ones you would find on the bottom of the cupboard door. They put it on the frame of the vehicle and that makes up for the gap.
