I believe this just happened after the latest update.

I enter math equations and constants for my chemistry classes using the advanced math editor. All of my previously made math equations in LaTeX now have "Latex: " inserted into the editing window. If I don't edit it and just close it, it's ignored.

But, if I edit the equation then I have to delete the "LaTeX: " or it's rendered in the equation.

I just checked and this doesn't happen with any new equations I type up. Only ones which previously existed before the update.

Anyone else seeing this?
