Altitude drifting issues

[BigDaddy505]

I have the DJI Mavic Pro and I have updated through my pc and done the imu and compass calibration. And all the sudden I take off, it goes to the 20 ft. Altitude level then just starts continuing to go up until it reaches the set altitude limit of 400 ft. What am I doing wrong? What can I do to change this? It happened before and I would just connect my drone and remote to the pc and refresh the update through the dji assistant program and then it would stop. Or I would just land, power-down the remote and drone and at restart it was fixed and mind you, this rarely happened. I just had the latest update of which I did through the app and then today I refreshed it through the DJI Assistant and it continues every time and nothing will stop it. If there were no altitude limit set, it would still be headed for outer space. Very frustrated. Please help me.

Have you checked to see that your gains are ok, try changing them and then resetting to default and re-calibrate, just a thought.

Omg. I did an adjustment not too long ago and I thought they were for the camera when it said "gain".
Thank you, thank you, thank you.
