3300 MRL occasional door staying open

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...

From the error log is looks like the photocell input is on alot?
Bad light curtain or maybe a defective door controller (Fermator?) Maybe try to bridge the photocell input for while, just to see any changes..

Replacing the light curtains next week, I believe the current ones are faulty
