I hope you are well today and thank you for your question.
The code that you have shared should remove the slider captions but as it’s not working for you then could you please share me your site URL so that i can troubleshoot why the code is not removing the caption?
I visited your shared site and found some PHP code is added in the style tag as shown in the attached screenshot which is causing not to work your shared CSS code.
To resolve this issue could you please remove this code if you have added it mistakenly in the Custom CSS field?
You can also use the following free plugin to use custom CSS code on your site.
I was thinking that Dazzling had the little Custom CSS area in Theme Options.
Would I also need that plug in?
And
I have a question about getting the slider across the top to stay (or appear / be constant) when someone clicks on a post. Can you help me with that or prefer I start a different thread (I’m thinking I did at one time…)

The plugin is an alternative if for some reason the Custom CSS option of the theme doesn't work for you so if the theme option works then you don't need to use the plugin.
