Wysiwyg is missing editing functions

I’m using the free version and I am following the documentation, but I noticed that on my site the wysiwyg is missing some editing fuctions that appear on the documentation. I’m missing the paragraph and headings, and without it my client will have to know html to add them. Is there a way to add these functions to the wysiwyg. Here’s the link to the documentation: http://masterslider.com/doc/wp/free/#slides and it is under Working with slides, slide info.

Thanks
