Wordpress Theme not displaying events correctly

I have purchased a theme and have been customizing it for a my perfumes diary website I work for . The only issue I have run into is a big one. The events are listed backwards in date. I want the next show to appear at the top and descend. But it is showing the furthest away date at the top. The theme gives you an option to sort the events “ASC” or DESC" but when changing the option it doesn’t do anything. It has to be something with the CSS / HTML code and I can’t find it.

Have you tried to contact the theme author for the free support?
