Pro, same thing at my local branch, manager not in

Pro, same thing at my local branch, manager not in today.Guy I spoke with looked up what he could and only could say that it was trades that transpired during hours that did not get recorded. It was outside our sector as well. He had no explanation why so many trades did not get recorded as or when  these transactions took place and said he would have manager contact me on monday. Only explaination was a system glitch!
