I don't see this listed in the issue tracker, and I can't find any good hits searching this forum, but for me the fuel-indicator on the POS REPORT page only indicates current fuel, not the fuel on board at the time of crossing. Indeed, watching the page, the fuel will tick down synchronized with the totalizer. FCOM 11.42.43 describes that it should work just like in the 777, showing the lesser of tot or calc fuel at last waypoint. So the question, is this just on my installation, or is it a bug?
