Sorry to bother you, this is an odd one...
There are 4 parts to a final Stack question in a Quiz, the LaTeX in parts 1 & 4 render without issue but is sporadic in parts 2 & 3. The questions render perfectly if previewed on their own, but when the test is being attempted, the [Math Error] appears as in screenshot.
> Moodle v3.5
Quiz questions are from last year and the question bank was backed up and restored as part of the setting up of this course page.
Any insight would be very much appreciated.
