PS5 Class 378 - Car-to-car Connector Bugs When Spawned On Wcml South

I have been recently having an issue when spawning the Class 378 from Incredible Trains' London Overground Mildmay line add-on on a service on WCML South on either end of the Watford DC line. For some reason, the car-to-car connectors either clip through the train diagonally, or they just don’t appear at all. This is present on both the 4 car and 5 car variants drivable on London Overground services on WCML South. I have no clue as to how this is happening. If anyone knows why, please let me know!
