[2] Your predictions are not overlaying well with the spots . Well it may be overlaying well with a subset of spots (in this case, the strongest spots that obey the symmetry *you* chose), but your are leaving out a large number of spots.
As I said before, your diffraction pattern is exhibiting strong reflections with weak reflections at a given resolution. It looks as if there are multiple lattices probably due to bad crystal morphology ( a cracked crystal, twinning, pseudosymmetry) or multiple crystals in the beam, the list goes on....
I've experienced your case many, many times.... you'll get a good MR solution, but then the refinement becomes 'stuck'.
I think the idiom... 'garbage in, garbage out' applies here..

Sounds like a file name problem.

There are a number of ccp4bb postings about crystal reproducibility or crystal diffraction improvement. Search the archives for these.
