Getting an error in the ADRV9009 Profile Configuration Wizard v2.3, "In frequency response commands, the frequency grid must be a vector of positive real numbers"

Setting all the sample rates to 78.125MHz, all the bandwidths to 64MHz, and the TX primary signal BW to 42MHz with ORx stitching on, and all the weights set to 1.  When "Generate Profiles" button is clicked, the pop-up progress dialog appears immediately followed by an error dialog with the message as stated in the subject line.  This happens for all sample rate frequencies below 100MHz.  At 100MHz and above it is fine.
