A section of my website loads slower than the previous

Hello there,

I have an issue with a section of a website I’m creating. On the homepage, there are some tabs that come from either the left or the right. Then, I saved them as templates and added them further down to display some different content.

The issue is that the first block of slides appears and gets loaded very quickly. the second one takes a lot of time to appear. Sometimes I have to reload the page to make them show up.

Both sections have the same settings so I don’t know what the problem might be.
