Hiding the byline only in events

I’m having a problem with the events byline (the author, date, etc. that gets posted under the event title) conflicting with this plugin. It displays the date that I created the event just like it would for a blog post, but if you don’t know much about WordPress you might think the date it was posted on is the date that the event is supposed to be on (it just says “on” instead of “posted on”, making it seem like the event is on that date). This website will probably be used by a lot of non-computer literate people that might get confused.

.entry-byline {
	display: none;
}

^^This works, but it hides the byline on my entire site, and I do need the date to be displayed on blog posts.

I’ve run across some other threads of people asking similar questions for different themes, so I tried this:

.single-ai1ec_event .byline
{
	display: none;
}

However, this does nothing. I don’t know if it’s because of my theme or if I’m missing something, but “.single-ai1ec_event” doesn’t seem to be a class for me, so the selector does nothing.

I’m using the Dispatch theme and here’s the events page of my website:

If you go into an event you can see how misleading the byline is.

Is there any sort of CSS trick or anything that I can still use?
