I think FF is not 100% accurate. I think if it makes sense to you (if you had other O signs), then I would assume you did O and FF just isn;t recognizing it. But, that is JMO and I could be wrong. Sorry to hear it is such a PITA though.
Also, sorry to hear about your VS mixup. The same thing happened to me one time. I was really upset about having to go out of my way for their mistake...aaaarrgggghhhh!!!!
I hope tomorrow is a better day for you!!
