Gallery options not working

Hi,

I use the Focal theme which is mainly based on the Heroic gallery plugin. The plugin’s options do not work. I made several galleries but all (except for the one on the homepage, which you can set in the Theme options) are displayed the same : a three column with image tumbnails.
Can someone explain how i can get the other kind of galleries? (for example full screen slider with horizontal thumbs,etc.)

Kind regards,

Monique
