WP 3.5 and Themeboy Football Club 2.0.8.3 – Featured Image Problem

Hi All

I upgraded my WP to 3.5 yesterday and had a bit of problem.

I am using Themeboy Football Club 2.0.8.3 theme.

When I use a featured image, it shows 2 full size images for the featured image. This is using the rotator function of the theme.

Before upgrading to 3.5 it would show 1 featured image and one thumbnail size image, but now its showing 2 full size images.

Is this a problem being cause by WP 3.5 and does anybody know how to fix this issue?

I have now downgraded back to WP 3.4.2, but I like the gallery feature on WP 3.5, so I would like to use it.

Any help is greatly appreciated.
Thanks
