Add an Expert Fields dissapearing & Digital Download when paying

Hi team,

I have a few questions now that I'm testing the Job & Experts plugin.

When I attempt to add a expert the fields (when I click on them) appear for editing, but once I confirm it disappears and I can't tweak it again. Same applies for all fields on that page?

http://seekir.com/add-a-expert/ (You need to complete the registration and add the coupon code: SEEK2016 when paying to receive the R0.00 payment option for bonus credit. Now once that's done the other question arises. In all invoices it shows a download option and I can't remove that or alternatively redirect clients to the main page or log in page. (Preferably I'll have it gone)

Also the side bar price slider doesn't work? http://seekir.com/job/

Sorry for all the questions!!!

Any insight would be great please. Thank you.
