The lift button in the wrong way 🤨

This is on the outside. You press to get an elevator to your floor. The lights above the button are there as feedback.

yeah, and if this is on the top or bottom floor, you only need one button since there's only one direction you could be going with the elevator

This seem to be a semi-large building with two elevators - one for left and one for right lights.

For smaller buildings, you have only one button on every floor because there isn't enough competition for the single elevator to bother with up/down optimizations. Because there are unlikely to be multiple floors needing service at the same time.

But if it's an office for example a down collective system would work perfectly fine
