Tabs On Mobile Dissapear Between 768px and 700px Wide

I am using the Vertical Tabs item of Shortcodes Ultimate on my site. I have several image galleries on my site. You can see one of the more complex ones here –>. https://www.sgclark.com/wallpapers/ncaa/

When I test out the responsive tabs on various device sizes, I’ve noticed that the tabs disappear when a device screen is between 700px wide and 768px wide. For example, when I look at my site on my iPhone 12 held in landscape view, the tabs do not display on the page. When I switch it to portrait, the accordion version of the tabs display as expected.

When I use a responsive simulator and expand the screen to 769px, the ‘normal’ tabs display and work as expected. Similarly, when I bring the screen to 699px wide, the accordion version of the tabs display and work as expected. However, when the screen is between 700px and 768px, the tabs are no where to be found.

Is this a bug within the CSS files/settings of the core plugin? Is this something that can be fixed so that at the 768px break point, any screen below that width has the accordion style? And any screen above that width has the regular tabs?
