Is it possibly being caused by surface contaminants on your PCB? Or possibly flux residue? Is this a one time occurance, or are you seeing it regularly? Is it happening in other areas on your PCB or in just this location? Can you please provide more

Try Easyspheres (Kester), or Q-Pearls (Qualitek), or Alpha. They all have solder spheres in that alloy.
