Issue description:
Expected: A Screen filled with Elevator entries should make the platform move to all "floors".
Experiencing: If a Screen has 12 entries (totally filled screen) any of the entries in the right column move to their counterpart on the left, meaning it only reaches half of the floors. So it is behaving like a long buttons instead of separated entries.
If you eliminate or add another elevator, since is not filled, it behaves as expected.

Steps to reproduce:
Place 12 elevator modules (either survival or creative), power to bottom elevator and place at least one Screen with an Elevator Button Module configured. Use a Screen Controller and scan for the screen(s).
With a screen full of buttons, it only reaches half of the elevators. Adding a new one or removing an Elevator behaves as expected.

This bug prevent having exactly 12 floors. You have to either build only 11 floors or 13. I think the maximum of an elevator is 16 floors, so 16 would be impossible as well of 12, because you have 8 floors on each sides.

For example, if on a screen you see:
1 7
2 8
3 9
4 10
5 11
6 12

Floors at the right of the screen acts like them at the left.
Pressing 7 will go you to 1, pressing 8 to 2, and so on.
If you remove the 12th floor, all is working as expected.

Not sure if I remember correctly, but isn’t there an option to turn off vertical columns and display them in rows instead? I think I remember the buttons are smaller this way and so it should work

Hello,

It seems this issue still continues to exist. Is there an update to this @McJty ?

Regards.
