Feature slider not working

The Featured Content Slider isn’t showing on my page. I have done as instructed:

– I created a category called “features” and included 4 blog posts
– all 4 blog posts have titles and photos
– Checked the checkbox in Appearance>Customize>Theme Options to “Use first image post as the featured image”
– Checked in Appearance>Customize>FeaturedContentSlider to show slider and set to “Features” category.

But the slider still isn’t showing up, may I have some help? Thank you.
