5 stop, through car, door 2 opens at only level G, and door 1 opens are every other floor.

Occasionally when the lift arrives at G floor and doors open, the doors will stay open, light curtain not obstructed.
But once you put your hand through and break the light curtain and take your hand away, doors will begin to shut and lift works fine.

There is no nudging (final timer auto close) feature on this lift, (is there a way I can activate via cadi/Bionic?)

The doors will just stay open forever, until the light curtain is broken and unbroken.

This has me stumped...
