Hi,
1/ I think you can installĀ this plugin and change the font size for that headings via your editor.
2/ You can hide it by add more this code to Customize > Custom CSS:
\
.penci-overlay-over .overlay-header-box, .penci-overlay-over .overlay-border{ display: none; }\
.penci-overlay-over:before{ content: none; }
Best Regards,
