Multiple Content Templates Colour Issue

Hi Guys,

I've follwed the steps in Leo's video on your docs for setting up multiple content templates based on Category.

I have a main content template that has a container block with a gradient on it applied to all posts. I then have another template that is similar, but has a flat backgound colour on the container mentioned above and gradient is switched off.

Setting on the element are:
Apply to: Posts with Term
Taxonomy: Category
Term Name: {my catergory slug}
Parent Element: {my main content template as mentioend above}

When I save this and view it on the front end, all containers have the gradient applied.

I can see in the inspector that all of the containers are being given the same GF unique class and the different styles I am adding are just being overwritten. (ie. all containers have the gb-container-0a8d5fa9 class on them, even though they are seperate Content Templates).

Any ideas?
