We do not have any repeating / recurring events, yet our entire Events List repeats itself on the "Events List" page. What you'll see is a chronological listing of the events and then when you come to our last published event, the list then repeats itself from there.
A ticket was opened, on another matter and this was added to it, as I did not want to wait the week already I've been waiting for my other issue to be looked at. The one thing in common is that neither issue was previously observed before the last upgrade / patch that was released and applied. After that we started to receive comments from users. It may have been earlier, but we have no indication to support that.
