Field in courseoverview not change after setting course

In page settings/details/{course_id}, I’ve changed value of short_description and saved. After refresh the page, I see the short_description of the course has changed. But after check in table course_overviews_courseoverview, value of short_description still the same. After some research, I’m confused where did short_description saved, I guess some field is saved in modulestore, some is saved in mysql (I don’t even know what modulestore is)

Hi @devpt, please check if you are affected by this reported bug, the situation you’ve described sounds very similar to it — Disabling entrance exams causes an error when updating course settings.
