Tour/tab videos not displaying properly

Hi, I’m trying to put an Essential Grid of Vimeo videos in each tab. But it only shows the videos properly for the already opened tab. Then when I click the next tab, it just has tiny little boxes instead of the normal size, until I refresh the page – then they’re normal size. I can even click the tiny play button in the screenshot and hear it, but I can’t actually see the video. This happens in Chrome and Safari.

But it seemed to only happen when I used the Highend tour or tab elements visually. If I just copy the shortcode for the tour, it seems to work. And that would be fine, except I don’t know how to make that look the way I want.

It is for a membership page at https://www.oxycise.com/videos-for-members/ – I can give log info privately once you respond. 🙂

Thank you in advance for your help!
