@Hyerlobos I think the yellow outline is showing the space sims need to use the elevator, and the common wisdom is to leave at least one free square on all sides of that. I'm wondering the same thing you are though: whether the fact that the outline is offset has anything to do with the problem. It looks like the elevator was originally placed on a half-square, either with alt or MoveObjects On, which could be the cause.
In this case, I'd delete the elevator and the shaft, plus everything immediately around it, and build the elevator from scratch. If you want to double-check your work, there are plenty of build tutorials on YouTube that do a better job describing the process than I could. If that alone doesn't fix the issue, I've seen a couple comments that deleting the trees in the lobby can help. And if that doesn't make a difference either, you can always delete and replace the building, or replace it with a different venue you like better.
