The cards get updated every month or so, but the card images haven't. You need to
clear the cache as it is showing the old images. Normally you don't need to, but for some reason we had to this time.
And the +6 doesn't mean you add +6 to the overall rating. What it means is when that image was created, his overall rating was 6 more than the original, pre-release, rating. For example, my image for him shows 66 -8 as the original rating was 74 (as with yours, 80=74+6).
