[JW Lua] Weird accidental behaviour

Robert, thanks for your suggestions, but I still don't get it.
Is there a way to detect this behaviour automatically in JW Lua or not?
Your suggestion "Move one accidental" is a manual step - or did I
misunderstand you?
I am looking for a way to automatically detect that this FCAccidentalMod
behaves differently or that there is a hidden FCAccidentalMod. Both
doesn't happen at the moment.
FCAccidentalMod:LoadAt always returns false here in my scripts (unless I
do some manual steps as in my Youtube video).
So I don't get this hidden default value -54 EVPU automatically, but
always 0 EVPU.
Manual steps are not possible here as this is part of my Perfect Layout
plug-in.
In Perfect Layout there is a comprehensive accidental placement function
which improves Finale's default placement of accidentals (e.g. move
closer together in some cases, allow slightly overlapping if there is an
accidental with parentheses, look at the shapes of the accidentals and
see if this allows for better placement (double sharps need less
vertical space than flats), etc.).
This works fine on all documents - except for this one.
Best,
Jan
