Carousel widget

Hi, first thank you for your widget. Everything works perfectly ! I would like to use carousel but I don’t want to show the image. I know it’s strange… I just want to display the title of the posts. I have tried with this :.sow-carousel-thumbnail {
display: none;
}

but everything is hidden, even the name of the posts.

Thank you in advance.
