How do I add time fields as text to conditionally calculated result?

The second issue is closer to being resolved. I'm trying to add the data from multiple fields into the "Your Date and Time Slot" field. I want the result to display like this:

8/14/2017  1:00 - 3:00

But what I currently get is this:

08/26/2017    13- 15

The fields that I'm trying to copy time data from are 1) Requested Arrival Time and 2) Choose a time 2 hours later.

Thanks,

Please edit the condition that currently add the values, set all the fields to be added as text by default: 

You can take a look on this form in order to see the result: https://form.jotformpro.com/72254980415963 

I hope this helps.
