Try pulling it all out and cleaning the whole area, with acetone, then put a very thin layer (a film) on the inner face of the BB shell, then insert the new bearings using a decent quality press that will keep the bearings precisely parallel to one another as they go in.
Make sure that they are snugged up against the circlips - this usually takes me a few gradually increasing tightenings to get correct, then install the bearing shields and the axle, spacers etc.
I suspect that you've contaminated the shell with dirt either during assembly or re-greasing.
