Quad tilting to the left

I have followed the steps to calibrate my quad and am having an issue with it being 100% level.
When I look in mission planner at the attitude indicator its not perfectly level. Its leaning about 2 degrees left. It also drifts that way slightly in flight. What do I need to do to remediate this issue? Im a total newbie here as well.
Thanks.

TC,
SaveTrim or AutoTrim will likely sort it out. There’s a wiki page here including a video of yours truly doing the trim adjustment.
