Hello,

As soon as I have deactivated the plugins https://gyazo.com/3fd28d8f85461cc1326a0bbef7da82ba
I have checked and it works: I have added a title to the HTML block: https://gyazo.com/7e9643f91c50b1c556372575ec24cd0a

I view the home page and I see this title: https://gyazo.com/a310d787ca516d608dfde0de08ceeefe

I removed the title now and activate the plugins.

Please deactivate all the plugins not related to the theme and check the issue, If the problem has gone, activate the plugins one by one, checking the issue to detect which one causes the problem.

Best Regards
