Global Variable issue with micron scale

I'm having an issue with global variables while using the micron scale. For instance: if i set a global variable = 10um, the 'evaluates to' tab says 10000nm, but on the actual sketch it evaluates to 10000um. See picture below:

Does anyone know how to remedy this issue?

I've had this problem for a while. I used to solve it my exiting the sketch and reopening it, which would cause the dimension to correct itself. Since i upgraded from 2013 -> 2015, this solution no longer works.

Thanks!
