Shifting layer - raster image distortion

Hi, Im trying to align numerous GeoTiff images (photogrammetry data sets).  Ive attempted to use the shift layer function both by the xy offset and the bearing option however on each occasion my raster is distorting.  The complete image doesn't appear to all be shifting along the same path, its twisting out of alignment.  Any advice please?

    I suggest that you contact Blue Marble Support directly via email ( Please provide a detailed description of your work flow, including screen captures of the options you are using to shift your data, and a raster data set that becomes distorted. This will allow the support team to attempt to recreate the problem determine the cause. Thanks.
