Where is a "Dancing Script" font loaded?
Those fonts above might be included with some old sliders provided in Blaszok package.
Related CSS code can be found in Slider Revolution->Slide Editor->Slider Custom CSS/JS Editor-> Edit Depricated Global Styles
The best approch is to remove fonts @import and copy rest of those styles into Slider CSS field.
For removing Depricated Global Styles use "Empty Global Styles" button.
