Add Knowledge Block button not appearing

[JM1]

Has anyone tried the knowledge block feature? I've checked the "enable blocks" for the KB I'm using. I created two knowledge blocks, but when I go to a new article, and try to add a knowledge block, the button to do so does not appear. It is also not in the form layout for me to add. Any ideas?

I should also mention, that I'm trying to create an article using an article template.

Opened up a HI ticket. You can not add knowledge blocks to article templates. You can only use when creating a standard article.
