Hi Joe, sorry it took so long to reply.
Normally the date you seem to be referring to is only listed beside the first event to take place on that date, which is a common pattern with WordPress posts too.
If you take a look at the list.php template that ships with The Events Calendar then you will see how the tribe_is_new_event_day() is used to control this – so you could definitely make a change here if you preferred the dates to show consistently.
You might find our technical documentation and in particular this list of loop functions to be useful here:

I hope that helps!
