[shared_counts] short code

It sounds like you may have added the [shared_counts] shortcode to your theme or a code snippet plugin.

The Shared Counts plugin doesn’t add that shortcode anywhere, but if your site has that shortcode then it will render as social sharing buttons. Since you’ve deleted the plugin, the shortcode is no longer rendering as social share buttons and is just plain text now.

I recommend either:

a) Find where you added the shortcode in your theme and remove it.

OR

b) Install a Code Snippets plugin and add this code snippet:

add_shortcode( 'shared_counts', '__return_empty_string' );

That will register the [shared_counts] shortcode and make it output an empty string so it won’t be visible anymore.
