Trying to view the contents of the Learning Center (https://learn.namebase.io/) causes the site to load fine at first, then after a second or so, the sidebar slides out, obstructing the contents of the webpage with no way to hide it. Tried this in multiple browsers with exactly the same experience. Please could someone look into this?

The pics show the page loading, then the sidebar opening with a cross at the top, then a split second later, the cross disappears and the namebase logo disappears
