Background of the issue:
I am trying to save the English translation of a project with an ACF flexible content field. When I delete a row in the English translation and update the page, the row doesn't get deleted (or some part of it), even when we opt-out the option to keep the order the same through all languages. Link to a page where the issue can be seen: 隐藏链接
Symptoms:
One of the timetable images should get deleted, but instead, I got duplicate images (which we never uploaded like that).
Questions:
Why doesn't the row get deleted in the English translation when I update the page?
Why are duplicate images appearing instead of the deleted row?
