Can't remove AdWords account
I have linked the wrong Analytics property to my Adwords account, now I am trying to remove the link.
Within Adwords i have removed the link, but within Analytics i cannot remove the link I get the message
This value must be non-empty.
When I checked the 'how to remove link' in Google helps files they write about a 'delete' button...I get nothing showing in my property.
