Please describe your problem clearly. Normally due to problems in the Phase detector output multi phase align with proper phase difference but the phase shift will be multiple of clock period. You can have look on self correcting DLL which has detection mechanism in PD. May be digital DLL helps some times.

Thanks,
Raj.
