[phenixbb] Group ADP not working

Dear all,

I am refining a structure (2.9angs res; P21) with phenix (Version:  
1.3b; Release tag: rc6; linux platform)

I want to carry on group_ADP refinement, according to the ('lengthy')  
command line :

phenix.refine eden_unique1.hkl hlcoeff_blur.hkl abril28_phenix.pdb  
input.experimental_phases.labels="PA_BLUR PB_BLUR PC_BLUR PD_BLUR"  
ordered_solvent=false simulated_annealing=false  
simulated_annealing.mode=first  
strategy=rigid_body+individual_sites+group_adp+tls main.ncs=tru
e main.number_of_macro_cycles=10 xray_data.low_resolution=15.0  
xray_data.high_resolution=2.7 tls_group_selections.params  
rigid_body_selections.params group_anomalous_1.params  
elbow.acp_A_pdb.001.cif restraints_edits.params  
convert_to_isotropic=true

everything works just fine (including correct handling of an 'unusual'  
ligand; selected NCS restraints; TLS; etc)...except for the group ADP  
: phenix keeps doing individual atom B-factor refinement

(e.g. these are some pertinent remarks in the output pdb

REMARK ****************** REFINEMENT STATISTICS STEP BY STEP

REMARK    3_adp:  0.2751 0.3218  -6.062715e+00  -5.947567e+00
...
and so on, always doing 'X_adp' (and not 'X_gbr') on the different steps...

starting from a single value on the B-factor column in the input pdb,  
of course I end up having individually varied figures in the end,  
which I don't want

I will greatly appreciate any help on what am I doing wrong.

Thanks,

Alejandro
