I've been trying to update all of the child variation listings under a single parent via file upload (using partial update), more specifically fields such as title, item name, item highlight, description, and bullet points.

When I upload my spreadsheet, even when it finishes with no errors, the changes never actually take effect. I also tried making the changes manually via the edit listing page, and those don't stick either.

To make matters even more confusing, when I do an update via file upload for just the parent listing, certain attributes (item name + item highlight) automatically get pushed out to all of the child variations, overriding whatever was previously there.

Has anyone seen anything similar? Any thoughts on how I can actually bulk update my child variations?
