Base Override disaggregation from 4-4-5 to week for Dec'12 is not working

Hi,

Demantra version is 7312. Base Override disaggregation from 4-4-5 to week for Dec'12 is not working. Post Dec'12, demantra is dividing the override equally across the weeks. For Dec'12 , the full override quantity at 4-4-5 level is allocated to the first week only.

Attahced are the screen shots. Any pointers will be helpful.

Thanks!
