Clone Module not working

I am editing some projects on my webpage. I would like to clone some of the modules I have created – for example I have a CTA button on the bottom of my page and I want to make a copy of it (clone it) and drag the copy up to the top. When I click the clone module button, nothing happens. This is for everything – I can’t clone any module (blurb, call to action, text… everything).

Up to today, I have always used the clone module function without any issues.
