Slider published but not displayed

https://sccft1950.com/test-2/?_thumbnail_id=266

Here’s the test page where my slider should be showing up. I do not have the Javascript error that other users seem to be having after a WordPress update. I’m seeing it in my developer tools, but I can’t figure out why it’s not viewable on the page. I can’t “preview” the sliders either. There’s also a slider on the homepage of the site (https://www.sccft1950.com) being used in the widgets “text-7″ id=”wd-slider-0”. I’d appreciate any help!
