Although this isn't a cure, you might consider opening up the review then using "CTRL A" to highlight all, and "CTRL C" to copy the review to your pasteboard. Delete the review. Next, start a "new" review and hit "CTRL V" to paste in the original review, make your changes, then save it. You'll end up with a different posting date than the original, but this will be a quick fix until you can get the matter resolved with BR.
