Sections break page numbering

Hi! I have a large document and wanted to create an automated way to insert the title of my sections within the document in every page’s top right corner: in this example, we have the section “group 1B” and “group 1C”.

But by adding sections, my total page number is messed up, indesign seems to only count up to the next section created. To go around this, I’m adding my total page number in the master page instead of leaving it as the variable Last page number.

Still, I wanted to know if there’s a better way to do this…

Thanks!
