pivot table not returning proper results with logic

i'm fairly new to excel (only been using it a few years) and i have had the same issue each time i have to use this file and i am never able to fix it. i have no idea if it is the logic, but the pivot is never returning the correct results in numbers. it can get a bit more complicated than i am putting it, but i wanted to put it here to see if anyone else could figure it out without having to get into the gritty details. i am not able to speak to the person who created it. however, i am the one expected to fix the issue and i havent been able to fix for months. i'm at a bit of a loss.

here's an example of the issue (this is what the numbers are meant to be)


This is what the numbers in the pivot table come out as:


I am wondering if the logic is off. i would like to thank anyone with advice in advance...
