Issue with CSS on Home Page
Have you tried disabling the equalheights module, perhaps it maybe causing this issue? You don't need a module to give blocks equal heights, when you can easily do that with css. 

I noticed on the top screenshot there is no video, while the bottom has a video.

Anyhow, based on your screenshot, it seems that you can fix this by adding a position: relative; to the div id or class that is wrapping the blocks. Which would be #block-views-featured-resource-block and what ever the name the Grand station Resource block id is.
