HTML tab code and Fluid Engine

Site URL: https://mountaintrailrv.com.au/

I have upgraded some pages of a website to Fluid Engine Blocks.

There is a HTML created tab that I want at the top of the page that has stopped working after activating it.

<div class="tabs-start"><h1></h1></div>

<div class="tab-section">Dimensions</div>

Is there an easy way of reverting back or do I have to re-build all of the pages from backups and not upgrade that particular section to maintain the HTML tabs?

Any help will be appreciated!

When you adding a section >> Scroll down to bottom >> You will see an option to add blank section -- + Classic Editor

You can add Classic Editor Section, you can also add FE sections on a same page.
