Fingering position, a property?

Hello, if I circumvent the automatic fingering position by Dorico, switching the property Slur-relative Position to „inside“ this property seems to not carry through to the parts if I Propagate Properties.
Is this by design?

It works fine here. Are you sure you’re propagating properties with the Notes selected?

Yes pianoleo, I usually select all of the specific flow, then Propagate Properties…
