When the form is loaded, it is already displaying some data. How is it even possible?

I have a form and before I save the link, it is blank - no information filled in. But when I save the link, it shows some information already filled in! Help - what am I doing?

Form:

AMSOV 2019 Resgistration

form link:

https://form.jotform.com/83284712140148

You might have enabled the 'Continue forms later' option in your form settings that saves the form filled information to the browser storage. Since the data is stored in the browser cache, it shall be displayed for the respective users. So, each time you open the form on the same browser using the same PC, the same data shall be displayed. If you open the form in a separate browser, it should be displaying blank. 

Hope this information helps!
