if you got structure from somewhere (not Phenix) with H already present 
and Phenix does not recognize them, then it's best to remove H:

phenix.reduce -trim model_with_H.pdb > model_no_H.pdb

and then add them back

phenix.ready_set model_no_H.pdb

then use the new file with H added from this point on.

Note, you can do both steps using the GUI.
