image service mosaicoperator does not change returned image

Hi,

I have a multidimensional image service published from a mosaic dataset and also one published from CRF. When requesting a range of multiple times and changing the mosaic operator from mt_first to any of the others the same image is returned. I have tried this with a range of 30 time-steps and mt_sum looks exactly the same as mt_first.
