I just created a reoccurring event on my live website and the Events archive listing page is showing a weird, what I assume to be, the creation date for the Event before the event category:
November 30, -0001 in Training session
Just to sanity check this I then created a regular event and its correctly showing the creation date before the event category:
January 23, 2013 in Match
This can be seen here.
I think that this is a bug but not 100% sure, if someone could please check it out and confirm?
