PerformancePoint Analytic Chart showing unformatted value of SSAS measure

I have recently come across some very peculiar behaviour of the PPS Analytic Chart where it for some reason showed values with a scale of 7 instead of the formatted value which has a scale of 2. To make this even more bizarre when you change the chart type to grid and look at the same data it shows all the values as zero (zero is the expected value in this case) with a scale of 2 (0.00).
