Air Bubbles only when Pump Starting

I’ have lots of air coming out of the returns when the pump starts. After a few minutes, no more air. The pump hold prime while off, so I don’t think it’s that. I do notice that when the pump ***** off, I can hear a “sloshing” sound in the heat pump. I don’t notice water leaking anywhere though. Any ideas?
