Xbox Series X Class 465 Missing Destination Display On Some Services Only

I’ve saw the onboard PIS for the 465 on SEHS working on some services but not all on SEHS

a 465 doesn’t have any destination displayed that arrives into Dartford about exactly 08:26:00 (this service appears to be the 08:27 to Charing X)

edit: after some looking into what the train was up to it turned on its PIS after sometime, (opened and closed its doors twice) and had no driver when it took off.

one left Dartford about 1 minute before this and that one displayed a destination

I also believe to have seen 375 have the same issue on all their services

700 works all fine and I think the 395 does aswell

edit: also saw several 465’s at Gravesend what didn’t have onboard PIS activated and it didn’t turn on when they departed like at Dartford (so possibly only activates when going off world?)
