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? (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?

Sorry for all the questions!!!

Any insight would be great please. Thank you.
