Fluid Brush style options not showing in UI, double click in brush library does nothing.

Not sure if this is an error or a limitation of the free trial.
I've downloaded the free trial of Adobe Animate and was especially looking forward to the fluid brush styles which imitate real world pen and crayon textures and such, but the brush style option isn't displaying on my UI at all. Under Color and Style only color shows. When I go to the brush library I'm told to double click art brushes to add them to the project. This does nothing.
My computer is only a year old and has decent specs (I'm still on windows 10 however), so I don't think that's the issue. I'm wondering if it's because it's the free trial and some options are limited? This has made a very bad impression, if that's the case.
