Once the bracket is full, it cannot be deleted. I know that.
In our case on the duplicates on St. A that got posted on Friday evening (due to WGT mistake), now 14 have no played in one, and 11 in the other. I don't want the duplicate deleted now because scores are up. And, I knew WGT customer service would not respond over the weekend, which is why I didn't ask.
But, I caught the mistake in 5 minutes from the bad post, and I could have solved it before anyone played, if I was allowed to.
