postgrid layout and categories

hello,

i have just purchased the postgrid plugin premium version and for some reason the grid layout is not pulling through the categories but also the homepage is not displaying my ‘health’ category. I have submitted a support ticket via the premium but I’ve not heard anything back. I really need someone to look at this.

Supposedly there is a way to add my new category to the postgrid so it shows but i dont know how to do that. and in regards to the grid layout not pulling through the categories I am uncertain why. Please help
