Hi,
You can try adding this CSS code:
.wp-show-posts-image.wpsp-image-left {
margin-right: 10px;
margin-bottom: 0px;
}
Here’s how to add CSS – https://docs.generatepress.com/article/adding-css/
Also, if the image is too big, consider resizing the image size display on Dashboard > WP Show Posts and open the target post list to edit.
On the “Images” setting, set your Image width (px) and Image height (px) to something smaller so the text will have space to wrap around on.
