SAP IBP Analytics Stories Calculated Measure not returning expected results

Hi assemblage members,

I person created a calculated measurement successful SAP IBP's Embedded SAC (Analytics Stories) arsenic screenshot below.

I was expecting the "Forecast Changes" calculated measurement to instrumentality the quality betwixt "Latest Forecast" and "Forecast Snapshots". However it was returning expected results successful lone 1 period (green rectangle) and thing successful the different months (red rectangles).

Both cardinal figures successful the calculation are stored cardinal fig with aggregation mode of sum and truthful are believed to beryllium capable to deduce calculation results of a subtraction.

Any insights are greatly appreciated.
