Videos show up in post but not under category

I embedded a youtube video in a post and that works fine.
When I click on the post in the blog, the video displays.

I attached the video to the “Thai Massage videos” category. On my front page I put a link to this category, but when you click on the “Thai Massage videos” category, the post shows up, but the video does not display in the post, only the text, as you can see below.

https://thaihealingmassage.com/category/thai-massage-videos/

When you click on the post title, then the video shows up.

My question is: how can I get the video to display when I click on the “Thai Massage videos” category link?
