Indeed, using this file in CCP4 fails with the message: "CCP4MTZfile: Mtz column type mismatch: I-obs(+) K-J CCP4MTZfile: Mtz column type mismatch: SIGI-obs(+) M-Q"
According to this http://www.ccp4.ac.uk/html/mtzformat.html#coltypes the I-obs(+) column should be type K, and SIGI-obs(+) of type M. It's possible that phenix does not follow that convention. As for R-free flags, did you generate them in phenix? If so, the refmac run with default parameters that pdb does during validation would run against about 5% of reflections (in phenix test_value=1, in refmac it's zero). I guess general way to avoid such calamity is to generate test set with freeflag initially. At this point, you can definitely use something like sftools to reset the flags so that your model passes pdb validation with flying colors.
