After many trials that did not solve anything I'm coming to the conclusion that there might be a bug with the \appoggiatura and the \acciaccatura. I did try the options you then gave me. (context \score \override SpacingSpanner.strict-note-spacing = ##t and also \override Score.SpacingSpanner.strict-grace-spacing = ##t) that both make matters worse further along in the score. All problems disappear when I delete the \appoggiatura with its notes.I have created a complete bare minimum of a trial, one bar, two voices. One voice has the \appoggiatura at which point the other voice doesn't justify the notes that go beneath the \appoggiatura. So if you have any more suggestions I would welcome them. If not I will classify this behaviour as a bug.

If anything it would be a feature-request (to be able to override the SpacingSpanner.strict-note-spacing for just a single measure so that you don’t run into the issues you have elsewhere in the score), as I suspect setting strict-note-spacing to true does exactly what you desire for this case:
