New to this - cannot edit text fields in hero slider

Hello everyone. I am new to webflow having decided to take the plunge after years working with wordpress. I am following a number of courses but of course am impatient and so decided to work with a template.
I am making progress however am struggling to edit a sub heading text that is part of an overflow within a hero slider.
Is this something to do with layers? Can anyone guide me with what I am doing wrong?

Hope you can help,
Thanks Everyone
