Preloader heading invisible

I can’t change the word in a heading in my preloader of a template I bought. Mainly because it’s invisible. I find the html code to export where I see the letters but I can’t edit that and I don’t know what to do with the exported code. If I could only make the heading visible or I don’t know what to do. I want to change it with my name.
