HYPERLINK prefix in all the hyperlinks in the document

Hi all,

I am working on a world document and it has several hyperlinks to my email, organisations websites, etc. I imagine I hit a shortcut or similar but now all the hyperlinks are shown as:

{HYPERLINK"mailto:my@email"}

or 

{HYPERLINK"link to the organisation website"}

But when I send it to other people, they dont see that. 

How can I revert this?
