Using Personal Defined Event Properties in Charts

I have recently created a new Formula/Regex based property that I plan to use to aggregate how often certain common page components are clicked over time. When I try to use this new property when creating a chart, I am able to select the property from the appropriate event, but the chart reports always show no values, as if the property value is not available to the chart I am trying to build.

I verified the property value is being populated correctly as the correct values are shown in the Live data feed as I generate events from the application. My custom property appears in the “Other Properties” section of the window.

Is there a limitation somewhere that does not allow me to use the value generated in personal properties for use in a chart?

Thanks in advance.
