Does the AD9361 Filter Wizard version 3.0 work correctly for receive FIRs?

When the version 3.0 AD9361 Filter Wizard is set to design a receive FIR filter, the FIR/halfband rate box in the lower right area of the screen is labeled "AD936x Interpolation Rates" instead of decimation rates as shown below.

Selecting an Fstop over half of the selected Data Rate for a decimate by 2 filter results in the error message shown. For a decimate by 2 filter, isn't the filter sample rate be twice the decimated output Data Rate? In that case, an Fstop less than the Data Rate would be valid.
