Confirmation Message Confusing and Incomplete

We have the RSVPmaker installed on our website and enjoy it. I just set up a new event for which we are collecting RSVP’s. I entered text in the box for “Confirmation Message”. Then I tried a test registration. The confirmation email I received included all the html language for my original Event Post and did not include the confirmation message I’d entered in the edit version of the post. How can I reverse that so the confirmation message is all that the person receives after submitting an RSVP?

Also the confirmation says if plans have changed there’s a button to click but no button appears. How can we make it appear?

I’ve tried unchecking the box that says: “Include event listing with confirmation”, but every time I click on “update”, it reinstates the checked box.

Here’s the page: http://midpenmedia.org/rsvpmaker/walk-of-dreamers-an-evening-of-stories-2016-6-29/

Here is what the confirmation email looks like:
first: Elliot
last: Margolies
email: xxxxxxxxxxxxxxxxxxx
phone: xxxxxxxxxxxxxxxx
phonetype: Work Phone
Guest: Sally Hayman
Note: We will arrive early. Very excited about this event!
