Why are the VOD, pre-emphasis, and slew rate parameters reported as -1 for Stratix® V, Arria® V, and Cyclone® V FPGA transceiver pins in the Resource Property Editor when using Quartus® II software version 13.0 and 13.0sp1?

Environment

    Quartus® II Subscription Edition
BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

Due to a bug in Quartus® II software versions 13.0 and 13.0sp1, VOD, pre-emphasis, and slew rate parameters are incorrectly reported as -1 for Stratix® V, Arria® V, and Cyclone® V FPGA transceiver pins in the Resource Property Editor.
