Decreasing margins between sections in lightbox

I have purchased and installed Lightbox Anything plugin for adding Lightbox to the Portfolio Hover layout on the website.
It works fine overall but there is a huge issue with the section margins. For some reason, Lighbox adds margins in between sections even if there weren't any on the original page which is redirected to the lightbox. I have contacted the creators of the plugin but it seems like they don't get the problem...

Here are screenshots of the original page and its formatting and the lightbox version. On the mobile version the upper title in Lightbox also gets a margin between the video.

Is there a way to code inject something inside the Lightbox plugin? I saw such an option in the manual but don't know how this command should be formulated.

Thank you.
