Even though I am logged into Hexus Trust, I can't edit the retailer ratings, I've given.

For example, when I select Crucial Technology and click 'edit rating' - it says:-

"Rate User - Unfortun8Squid
You cannot edit a rating which you did not make"

or

"Rate User - Toby G
You cannot edit a rating which you did not make"

Is there some sort of database field mismatch going on here?
