Autofill Or Auto Correct Issue In Mac Mail 10.3

[smiffffffy]

i have typed my website address into mac mail 10.3 incorrectly when composing a message, i inserted a comma between the .co.uk part i.e. .www.vinylight.co,uk
The autofill or check or whatever checks for a web address and highlights it blue and underlines it as a hyperlink to my site only highlighted UP TO the .co part and has left the .ukpart as normal text.
I corrected this mistake and now every time i try to write my website address it auto fills it in exactly the same way, as if it has remembered the mistake as its correct version of the auto fill.
It works ok in word if i open so it isn't all programs on the mac but only seems to be mail.

Does anyone know how i can make the mac mail forget the incorrect autofill.
this is an absolute pain as the hyperlink will not direct to my website, and the link is not written correctly
regards john

Start a new message. When you type start to type the address & you see the wrong one hit the blue circular info button next to wrong address & remove.
