Does anyone have any issued with Billed and invoiced time showing up as Unbilled even though it was billed and invoiced correctly but a portion was Carried Forward.  (ie total WIP 2450 - billed out 1925 and carried $525 but still showing as unbilled on time entries for the whole lot)

I have two situations where I have billed a portion of the time and carried forward the rest but in the WIP and unbilled areas the whole amount still shows as unbilled. Any ideas?
