Another instance of the issue: Pro Macros started relying on the MathJax Macro with version 1.14.0. MathJax optionally depends on Latex extensions, which are not useful in the case of the Pro Macros. 1.14.1 excludes the LaTeX extensions to fix some issues they may cause under some situations (besides being there and taking resources and still be unused). Upgrading to 1.14.1 does not get rid of the LaTeX extensions.
