Slider component: How to edit textblock - slider mask always on top


I’m new in Webflow and check some components to know, if I can use webflow.
I worked trough several video courses, docu and forum.

My problem:
I have take the slider component and add on the slide div blocks with svg and textblock.
I can’t edit the text to change the lorem ipsum to my text.
There is always the slider mask in front and it is not possible to grab and edit the text.

I think it must be a little handling problem from me,
in the slider video lesson there is demonstration to add the textblock - but they don’t show how to modify it. claro, it must be there of course.

Thanks very much for the help !
