Matrix Row & Column Grand Total Issue

[bbotros77]

Hello 

I am using Matrix Visual that inlcudes a list of Projects ID s and Size . I noticed that the Column Grand Total in the Matrix is not considering all Sizes. So for example Matrix shows 100 projects with Total Size of 500 kw but when i get the list of individual projects and sizes , I have 00 projects with total 510 kw. 

Any clue why Grand Total in Matrix may disregard some entries ?

Thanks
