Brian, Your receiver has only a single tuned circuit before the mixer, so I would not expect great image rejection on the highest freq band. Even when properly aligned you will still hear the image, although it should be a bit weaker.

I am not sure if it is high side or low side injection, but you might just try to set the LO to select the mixing product that allows the LO trimmer to be closest to the center of its adjustment range.
