Weird back tick characters appeared after downloading plugin

Hi there, there seems to be these back ticks ` appearing in random places all over my site ever since I downloaded the plugin. They only appear on desktop, not mobile.

I managed to remove most of them but they continue to appear as I add new content. Please see the link below:
