As reported there are two labeling issues.
1. For upcoming events and past events the date on the top left in the box says "Sept 5" . the recurring events be it on the 13th or the 27th of October are not Sept 5. I'm uncertain if this is the date of initial publication but the recurring events are ALL labeled "Sept 5".
2. For past events the tabs for the open browser windows read "Page not found". The event is there in the archives. This appears to be a glitch.
