Card showing the wrong name


I have set up a Twitter Card correctly (as far as I can see!) However, sometimes it displays another users name at the top. My name is @elcaminob and sometimes the card links to a user I have no connection with whose name is @elcamino. Does anyone know why this would be?

My card script contains the line:

I would have thought this would be enough to ensure the card is linked to @elcaminob not @elcamino?

Any thoughts or suggestions would be much appreciated!
