Moving groups of grace notes rightwards

The groups of grace notes are encroaching too far leftwards in this section. I’ve tried using Engrave to move them, but they seem to respond differently to standard notes - indeed they seem to move in the opposite direction to the arrows. How should I shift these groups (and whatever else needs moving) to the right so that it looks right?

You want the grace notes to only visually start after the triplet chords in the upper stave? If so, you need to move the main rhythmic notes in the bottom staff rightwards, and the grace notes will follow.

That’s bang on - thanks, Daniel. For the first group (and similar ones later on), I discovered that I also needed to uncheck the ‘grace note before barline’ option for it to work.
