glitchy position on click

I having a look at the free version and for a front end visual editor, it is pretty impressive. I have one recommendation though without complaining. Every now and again, when I click on an element, the element jumps off set and it is a mission to re-align. this is obviously a glitch. besides that, as I am playing with the editor it is still great. I can edit woocommerce product pages and use siteorigin(backend) and the combination is terrific.
