Flow Title when flow starts on same page

I managed to let a new flow start in the same page as the last one ends, but Dorico doesn’t generate a flow title here. There was a title when the flow started on the next page, but it was gone when I shifted the flow.

How can I get a title in this spot?

Do you have a Page Override already on that page? Does it show a little red triangle like this in Engrave?

If so, remove the Page Override then see if Dorico correctly recalculates the page and adds the Flow title.
