The problem of range filtering for TanDEM-X dual-pol data

Hi,

Does anyone have any experience with range spectral filtering on s1tbx1.1.1 and TanDEM-X CoSSC data? Applying the s1tbx1.1.1 Range Filtering (Interferometric\ Filtering\ Spectral Filtering\ Range Filtering) on an interferometric stack with dual-pol (HH and VV). The generated result only contains VV polarization. The results of HH-pol are missing.
