I'm not sure if this is a one-off thing, but I've just gone into my 'events' listing and it comes up with the same three act line-up I added about 2 weeks ago repeated about 10 times. The reason I went into the section in the first place is I need to change the line up since one of the bands has had to pull out, and there doesn't look like there is an option to alter the line-up once it has been entered.
