This is a duplicate of #3336, and is explained there. Put spaces around the less-than sign in order to prevent what follow from being treated as an HTML tag by the browser. See the documentation for more details.

Have you found a solution? If we cannot modify the source data, what methods are available to solve this issue? @dpvc

@Daisy1213, the solution is to use spaces around the less than signs, or to use either < or \lt instead. This is not something mathJax can do anything about, because the interpretation if the < as the beginning of an HTML tag is done by the browser long before MathJax runs, so is outside of MathJax's control.
