Your account is fine and it’s now fixed. It’s a bug that I’ve tried to fix at least three times and I have no idea why it continues. It only hits every tenth transaction, but for some reason it gets duplicated 2-3 times. All it ever doe sis give you a free extra year of premium, so I don’t sweat it that much, since you’ll still get auto-charged. Plus I built a cleanup script that runs once a week to automatically fix these. But you saw it before the cleanup ran.
Not sure what to do about it other than pencil in another attempt at fixing it.
