Hi,
I dont understand why you rated the theme 1 star, when I replied to your forum post within a few hours.
The issue you are having is caused because the “Title” field of each slide is required. While you add a slide, You can see that its clearly written “required”:

And its also mentioned in the FAQ section under the Theme Options > Documentation FAQ:

I understand, you missed those, but why 1 star? Can you please check again and kindly consider changing the rating?
Regards
