I don't know why you're calling 3x the same FORITEMS loop, but DCLICK function is the same thing as make the char dclick the item, so the item must be in range/LOS otherwise the DCLICK will fail, and that's why the 2nd door doesn't open/close when its out of LOS or distance is > 2 tiles. To fix this you must replace DCLICK with USEITEM, which is the same thing but USEITEM will ignore dist/LOS checks

Or you can manually link the door on each other (just use ".xlink" command or set LINK=012345) instead use this script, this will make sphere internal code automatically open the linked door
