Dynamics AX 2012 Project Management budget issue

Hello,

I have case regarding "Dynamics AX 2012 R3 Project management and accounting", when comparing consumption against Actual amounts on a project category/item level, the budget consumed amount is not equalling the Actual Amount, it's not the same case for all the lines so some lines matching some are not, it causing a big issue as the actual is higher than the consumed and some times it passes the budgeted amount, but the system is reading from the comsumed amount when it comes to budget control, any thoughts?

Used versionL: Dynmics AX 2012 R3 CU13

Thanks
