LMS 7002M Tx Filtering with GUI suite

I am using the LMS7002 EVB for an RF program but there is a little problem with the GUI operation. The DAC frequency is 10M and the maximum frequency of the baseband signal is 1M. When I am going to use the Tx Filter with 2M of the Ladder BW and 1M of the RealPole BW, it shows that the tune is failed and the Tx calibration is failed. The warning window also shows that the CSW_VCO_GEN selected 255.

Thanks for your help.
