PBCS CALC Script - SET FRMLBOTTOMUP ON; issue

Summary: calculation not working when SET FRMLBOTTOMUP is ON

Content (required): Hi everyone, I have a calculation script that will calculate expenses based on 3 month historical average. The issue before is that, the calc script takes 10 - 15 mins to calculate. I posted a question on the community before and someone suggested to add SET FRMLBOTTOMUP ON; This improves the calculation by a lot. The problem is when I launch the script and drill to level 0 members, there are some intersections that weren't calculated/not being calculated properly. Code snippet attached
