If you're using the standard cap reference method to align it, the blades very likely aligned. I'm thinking that it's probably just unsettled technique with the 37c at work here. Note, when you look at the razor from the shave side, you will see a difference in the guard/blade gap from left to right along the slant. This is normal.
