Try opening the other door and see if it turns the other way. If it doesn't then it's a curly-wurly propwash effect.
Incidentally, the force required to open a door in flight is a fascinating subject. I once spent 4 hours in a witness box being cross examined by a QC about it.

It works with both doors, rolling away from the open door. The more you push open the door the faster it rolls.
All very controllable. Ignoring spiral stability effects, the roll stops once pressure to open the door is removed. The a/c can be rolled upright by doing the same to the opposite door.

Wonder if you could control the plane by linking the yoke to each of the doors,with springs perhaps.
But of course youd need to learn how to adapt your flying to suit.........and we could call it.........
