Hi Chase,
You can achieve the same thing by setting AddUpperLower to False so that it doesn't add the "Upper Case" or "Lower Case" prefix.
FormShield itself doesn't have a CaseSensitive property value... Are you using it with StringCompareValidator?
If so, there isn't any integration between the two, i.e. FormShield doesn't know anything about StringCompareValidator and vice-versa.
