Normal text does overlap caption

I just found out some things:
I put in an additional image at the bottom of the page (the same image, but it’s a normal image, not a featured image).
There I set the same Text as description and activate the option to show this text.
Then this will look perfect! (top on screenshot):

I then noticed that firstly a DIV is used there and not “figure” and “figcaption”. Additionally the class “w-image-description” was used instead of “wp-caption-text”.
In the settings of the extension I specified that it should also use “w-image-description”. Unfortunately, the result doesn’t look the way I want it to (below in the screenshot).

What can I do to make it display correctly on any device?

Hi @synormedia
Sorry for the late response. Since the plugin adds the minimum possible layout styles, the way it appears depends exclusively of your theme. Also because of how css works (as you discovered) a class that works in a specific position (i.e. inside the main content) may not behave the same way in another place (outside it).

After checking your site link seems that you already solved it using the adding custom styles option. Another way would be to customize your theme CSS wich may allow you more flexibility
