I'm glad you caught that before I took it on a trail. The derailleur is low-clamp so I assumed the guide should be too. I'm going to return it and get a high-clamp. I may check with my lbs to see if they have any guides before I order another e.13.
It looks like there is a spacer on the bb, but I didn't want to mess with it (press-fit bb) and the ring spacers are plenty long anyway. However, the guide can't move any farther in so I can't use the spacers anyway. I would need a guide about 4 or 5mm closer to the seat post.
And yes, I know it should be lower but I couldn't for some reason. I've already forgotten why.
