Not working Properly!

Take a look at https://www.impishlee.com/customizer/

There are two buttons on the right hand side in a small “bar” – one called “Video Help” and the other called “Fabric Info”.

They are coded as fancybox-inline div elements that are displayed when you click on the buttons.

So… here’s what’s happening, they work when the page is initially loaded, but only one works and then the other doesn’t, or they both work, but then you can’t close them, or they don’t work at all! Can’t seem to figure out what the problem might be? Help!
