I have a fairly specific issue, regarding the TeX notation in the equation editor, displaying a '|' vertical bar at the end of each equation. Any help appreciated.

eg. Equations such as this;

**\( \epsilon _{Ni-718nm}=\frac{0.750}{0.04814Mcm} = 15.6M^{-1} cm^{-1} \)**

Render with an __unwanted__ '|' at the end of each equation.

Yes: I have checked the equation editor over and over and also the rendering HTML.

*Note: This issue didn't appear until a few days after creating the equations. *
