Resource Loading Tabular Report

I am have a lot of problems producing a loading for a resource in the Tabular report - resources - resource loading reports - RL03 Resource loading activity summary.

For some strange reason the total resource spread each year is not the same as the BQ in the P3 file or total in the toal column and the shape of the spread per year is not as per the resource ID curves specified.

Any clues ?

Thanks
