Weird Experience with motive brake bleeder

I picked up the the motive brake bleeder and some ATE DOT4 and bleed my brakes this past weekend on my 550i. I followed the instructions precisely and as I started out, everything went smoothly for both rear wheels.
When I did the passenger front, right before I was about to close the bleed valve, bubbles started to come out. I stopped, checked the MC, and it was at the max line. There was still fluid in the motive container, but I added more to it and made sure bubbles aren't in the line leading to the MC. I started up again and more bubbles started coming out. Before things got worse, I stopped, and switched to bleeding the old fashioned way with a brick behind the pedal.
First few presses were soft and had bubbles coming out. Then it went back to normal and several presses later, I switched to the driver front, and no bubbles came out from there.
I tested the car in the driveway - everything felt normal, I tested it out on side streets - everything normal. Then I went on the highway and tested them on a straight exit ramp w/o traffic near me - I went on them hard and it slowed down in a straight line. So it's safe to assume there's no air in the lines.

Has anyone experienced this with the motive brake bleeder? Did I miss something in the procedure?

Are they large bubbles are just very small ones...?

I've not used my Motive on my E60, but sometimes I get really small ones on my STI, almost like weak carbonation.

This isn't a problem with the brake bleeder, you had air in the braking system/lines if you saw bubbles and that's a good thing to get it put of the system. I've used Motive and other pressure bleeders for 20+ years with no issues.
