Intrusive humanization

Hello!
While hearing just written scores I discover that some chords sounds with a tiny arpeggios.
I record midi from Dorico to Cubase to see what messages Dorico sends, and yes - notes are not in grid precisely, as they are shown under “played duration” bottom in Key Editor in Dorico.
I turn off all humanization I find in Playback options, then reset overrides. It helps a little but the random positioning is still here.
In this image the last test is shown.

Is there a way to interpret what is written perfectly?

Can you adjust this:

Thank you.
But I already do it first of all…

Also this setting affects how the notes are displayed under “played duration” buttom…
In my case they are shown perfect in grid.

Not sure but maybe the setting only applies to new notes onward not retroactively to already entered notes. But we’d have to experiment.

Can you supply a document that shows the problem?

Hmm… Not sure I understand what kind of document you mean?

Upload the affected Dorico project file itself.
