Mainbody frontpage - Mainbody only

Hi everybody

I've just started with postnote template and know there is a little question.
What have i done yet:
I'm using top1, top2, top3 for my layout. In top1 there is the main menu and in top2 and top3 i would like to use gk news pro. Everything looks fine at the moment. Next i switched off the mainbody frontpage to mainbody only. So know there is no mainbody on the start page.

The problem is, that when i want to display any news from gk news pro there is no content displayed anymore. Do i have to fix this with a template override.

Hope you understand what i would like to doo.

greetings from switzerland
