My guess is that whoever entered them for subs, manually entered them, instead of doing the club coach account search, which brings up all of your clubs wrestlers. You then can click on the kids names that you want to enter, and it will bring them up in a window, where you check their usa card number, age, weight, etc before saving that info to the system. It is much faster of course than startingover and "adding a wrestler".
I noticed yesterday when searching for wrestlers, that sometimes it would bring up the same wrestler twice and if you click on one of them, it showed no info, and if you clicked on the other, it had their full history.........
