The inside of desert temples is asymmetrical: in the bottom half of the pyramid shape, the wall on the right (when facing the entrance from outside) is closer to the small pillars than the left side, touching the pillars even. The left side also has a layer of sandstone that fills the 1 high area for the same distance.

This appears to be caused by the outside staircase-like generation that leads to the top half of the structure, as these blocks stop when it ends.
