### Newly written problem won't show in HWSetEditor

First, WeBWorK, PG are updated to the latest stable versions.

I just wrote this problem. It won't display in Hmwk Sets Editor (MathJax nor Images), but displays just fine in Library Browser and Homework Sets.
ERROR caught by Translator while processing this problem
This is the only thing that shows up in Hmwk Sets Editor, whether rendered with MathJax or Images. As far as I can see, the problem works fine when assigned, or when browsed in the Library Browser, but looks like a failed problem Hmwk Sets Editor - which is fine for *me*, I know better, but when sharing with colleagues at my institution, I don't want them to be unnecessarily concerned.
