Superscript of \sum cannot be rendered properly

Created by: memakura

When I use \sum_{i=1}^{n} x_i without other equations, it seems the superscript n cannot be rendered properly. (n becomes a subscript together with i=1.) But when I use the equation with other symbol, such as \int_a^b, it works.
