Form needs adjusting

We have added the API to the website seaanz.org (still in testing mode). There are two products listed in the dropdown to choose from.

Q1; Why is there an item of AU$00 shown and can you point me to documentation to fix it? screen shot https://prntscr.com/1g2k4pg There are two products in the drop down, member and non-member price.

Q2; It is confusing when the email goes through to the buyer, showing Item Price: $0.00 then a final price which is correct. screen shot https://prntscr.com/1g2kuz0 Is there a way to fix this?

Q3; in the above snap it shows download link. it isn’t a download but goes to the original page. This is fine except for the wording. Is there an option to change it for the product listing?
