Xbox London Commuter Trains Onboard Pis Set Not Working Properly

When setting a destination on the LC Class 377 it sometimes switches to another option, one time this often happens is when pressing exit on the control screen in cab for it

it can also happen randomly going when operating the service

Edit: this issue also occurs on the 387 and can change pis at objective markers when there met

This was noticed on service 1W12, I set it to Brighton at Victoria and at Gatwick it changed to Gatwick
