How can I stop email autofilling on form with previous entries

When I input entry on a tablet previous email addresses show when I click on the email entry piont.

Can I turn this off.

I got the following message when I open the form you provided. 

Is this the form you have issues with https://form.jotformeu.com/iwdmagazine/RDSSept2017

Most likely the email address was saved in the browser cache and you can clear the browser cache to see if that will resolve the issue.
