Embeded Div is blocking its parent linkbox in published site

I have a problem with a link box; the embedded div in the linkbox graphicdesign and socialmedia appears to be over the parent link box in the published site, if i hover over the linkbox in the published site, the embeded divs are blocking the link, but why?

The embedded divs are children of the link boxes.

I tried to give the link box a higher z-index and give the embedded div a lower z-index, but it seems like the embedded div is ignoring the z-index.

The issue appears on all browsers.

The problem is not happening with images or other divs but only with embedded divs.

Please tell me the solution to my problem
