Hey @nicmare, Hey @mplusb,
we experienced exactly the same issue and after a lot of research we finally understood the cause. Since the database cells are updated when changing the order via Drag & Drop we thought there must be another reason because WordPress seemed to ignore the menu fields.
In our case it was the object cache, because it caches every database query, and changing the order via Drag & Drop doesn’t force the object cache to clear, a click on “Update” f.e. does.
I guess this is a very important thing to know and maybe you as plugin developers could take care of that, because Object Caching is a popular method to improve your site’s speed.
Best regards
Lukas
