Headline change and Breakpoints of the theme


I purchased The7 Theme and I have an issue with a headline at the bottom of the portfolio entries. There is a headline at the very bottom of each portfolio titled “check out our other cases” I need to change this headline but I can’t edit it with elementor. Can you recommend a plugin I can use so that I can change this headline?

I have encountered an issue with the breakpoints of the theme. Every time the width of the site is reduced below 800p the menu disappears. I tried to fix this in elementor by adding a hamburger menu at a breakpoint of 760p but the menu still disappears. Can you please offer a solution to this issue, since I believe this to be an issue with the theme and this is very bad for mobile accessibility.
