AD9361 Filter wizard crash

I tried designing FIR interpolation filter using the AD9361 Filter wizard. The data rate is 60MHz. FIR interpolation factor is set to 2 (After upsampling by 2, the FIR interpolator would run at 120MHz) and the Tx DAC is set to run at 240MHz. Fpass = 20MHz and Fstop = 25MHz. The wizard crashes and hangs. Please find the wizard screen shot and command window error messages below:
