Can't edit Jumbotron Text or any other

It seems that I can’t edit default texts within the theme. There is no editable panel as you can see below.

Hey there,
I hope you’re doing well today

I’m seeing the editing boxes. Is that when you make a change, the texts don’t change.
Or is it that you are unable to click in the box and edit the text?

As a troubleshooting step, kindly disable any third party plugins you may have installed.
If this resolves the problem, activate the plugin one by one to find the culprit.

Best Regards,

Thanks for the reply.

It’s the second thing. I’m trying to edit, the box opens but I can’t edit. I even tried different browser (Safari) and still them same.
