No available appt's on my calendar page, only 1 site

This is working on my other sub-sites but I just have one site where the available appointment dates are not showing in green:
http://evantage360.com/cbonal/contact/

This happens and I can usually find something and get it to work but cannot find the issue with this one. We are just trying to set it up for the first time, how can trouble shoot or maybe reset everything to default settings to start over?

Any suggestions appreciated, thanks!!
I will go ahead & grant access since that is often asked for :slight_smile:

I haven't updated to the latest version yet as I have made some customization's but figured if they rest are working fine I wouldn't have to update yet, hope that is the case.
