Repeat Events: End Date Display

[clayalabama]

Using repeating events on two different days. One shows the End date in the pop-up, the other does not.

I would like them both to NOT display the end date as there really is NO end date to these events.

Can anyone think of a reason one would display this and the other would not?

to take a look at the calendar: http://www.clayalabama.org/events.html

Thanks in advance.
