Possible Conflict Between KDS PE and RM

I believe that I have found a conflict between the KDS PE error checking for component pin use and the Reference Manual for at least the K21 chip. In the RM for the K21 subfamily (Number: K21P121M120SF5RM attached), section, the chart lists pin ADC1-DP0 as a possible single-ended pin for ADC input. However, in the attached image, KDS (version 1.0.1) reports a hardware error if this pin is configured in this way. A similar error occurs for pin ADC1-DP1. This conflict likely exists for the K22 chip, although KDS has not been tested for this case. Curiously, the error does not occur when the ADC1-DP0 pin is used by ADC0 (This pin is weaved with ADC0-DP3). Between the conflicting behavior in KDS and the RM, I believe this to be a bug. Let me know if any more information is needed.
