PS5 Class 66 Introduction (great Western Express) Brake Pipe Not Releasing To 5?

It looks like I completed this pre-remaster (shows gold), but as I re-attempted all again just to go through them, I’m curious to know if there is an issue, or if I’m doing something wrong when trying to do the brake test after startup? I cannot seem to get the brake pipe needle to go beyond about 3.8. I have tried a few things even not indicated in the tutorial instructions to try to help such as releasing parking brake, moving to forward from neutral, using the screen above to cut out the brakes etc… nothing appears to make this work in this tutorial to get past the release point.

Of note, the actual training center module for nearly the same same introduction DOES work and releases to required 5 as expected, so it does seem the module attached to the Great Western Express only has the issue… or a step in the process I’m not aware of that needs to be also done that may be restricting it.

Either looking for advice or reporting an issue.
