Theme stops my calendar plugin from working

I like this theme but I installed Birchwood appointments and it will not work properly. The setup for the appointments calendar has “locations”services” etc. which should show up on “Add Locations” etc. as a list of fields – using your theme, the fields are no longer visible in the setup – just a title field – Strangely other plugins appear below these settings sections such as Authorsure and Yoast –
the settings for the calendar are like categories/posts so I think your theme is confused as to what they are for. or how to display the fields in them.
