Looking at the demos here – https://demos.wpshowposts.com/cards/ your screenshot seems to be set to one of the Overlay styles rather than Polaroid.
Can you double check its settings?
You can change the text, title and read more button on WP Show Posts > Contact settings.
As for Social icons, these are set on WP Show Posts > Social settings.
From there, you can try matching what is shown on the demo. 😀
Note: If the settings doesn’t apply after saving changes, you may have to clear WordPress & browser cache.
I would like to send you the website in private.
