Custom story point values not adding up in plan view

Our team is new to RTC. One of the first changes we made to customize was to assign additional story point enumerations as we have been using different numbers than the traditional Mike Cohn set.

The problem is that when we assign a story to a different value from the original set, the plan document counts it as 0 points. If we choose one of the original values like 8 or 13, then it counts it correctly.

Did I miss a step in configuring something?

Thanks
