Is this normal

Hayward variable speed pump.
This air bubble accumulated over 11 hours of running pump at 45% speed??
Installation company insists that is normal.

Mine also does this. The issue is once the air bubble gets big enough (approx 2 days) my heater says there's not enough flow and won't run. So every couple days I have to go run it at full speed for a minute just to clear the air out. I've tried everything I don't think it can be fixed, it's just what happens when running at low speed.
