wp bakery issue

Hi, I have recently begun learning and using wp bakery in order to build/rebrand this site, i am accustomed to web development and for the most part have got the hang of how to navigating this page builder. Yet, when i update and view the page, i can still see the outlines of some of the blocks. Can someone please tell me why this is and how to correct or remove them please. Any assistance with this is greatly appreciated, many thanks.
