phenix.refine does a basic check to see whether or not the data is 
twinned. In this case, the refinement engine thinks data data might be 
twinned.
Please run

mmtbx.xtriage refinemenet_results_data.mtz obs=FOBS calc=FMODEL

to get more clues why phenix.refine thinks why the data might be twinned.


If you have problems intepreting the xtriage output, let me know, I'll 
give you a hand.
