Issue with Current and Last Instance Power Headers Forum

Hi, when using the current and last instance in a header, I have a scenario where it is not accurate:

I have a set up with chapters and sub-sections on the page (e.g. the header displays 1:1-9, 1:9-13 using current and last instance) and it works beautifully after a Global Grep.

But when a new chapter starts at the top of the page, the first paragraph on the page will be the new section title, followed by sub-section 1, but power headers is still pulling the previous pages sub-section number because the new source text is not the first line on the page – so, for example, it ends up saying Chapter 2:9-2 instead of Chapter 2:1-2.

So is there a way to tell a variable to ignore (or skip) a certain paragraph style (chapter number) at the top of the page?

Thanks
