The FO is pressing the Doors Button, which is normal during the pre start procedure, however, the FO is not pressing the button again to clear the Doors display and move to the automatic change of systems displays that we expect during departure.  Is this a known issue or am I missing a step somewhere ?

I'm pretty sure the Airbus should change the display automatically, unless FBW is not modelling that.

 

Bryan, that may be it.  I am used to it changing automatically in the FSL version, just thought it was driven by the FO.  I will pay closer attention next time and unclick the doors button if it remains engaged.

This feature was working in earlier FBW releases and stopped working after an update, which, unfortunately, is often the case with MSFS & FBW, not blaming anyone, just saying. E.g. if you fly the FBW A32N then you've probably noticed the ND Terrain button now says INOP after the last update. I expect these features will be reimplemented in due course.
