I tested this on wordpress install with version 4.8 and it works great for me.

This is most likely caused by the plugin, so I recommend temporarily disabling your plugins until you find out which one is causing the problem.

Start by disabling the plugin, which adds the sidebar visible on the left.

Then contact the plugin developer to find out if this is a known issue.
