I think the blade has a decent amount of clearance from the sides of the container; perhaps more of a misalignment situation?

If the pint is frozen unevenly, put the pint in the fridge to allow the ingredients to melt. Then whisk to make sure the ingredients are combined. Refreeze, making sure to place the pint on a level surface in your freezer. - To avoid damaging the unit, DO NOT process a pint that has been frozen at an angle. DO NOT process if the pint has been scooped out of and then refrozen unevenly. - Always smooth-out the surface of your ice cream before re-freezing.
There is no minimum fill line. We recommend filling the pint at least half way to the MAX FILL line to achieve the best output texture. Filling below this level will not harm the machine, but adding a very small amount of ingredients to the pint may result in an output with suboptimal texture.
