does the show more option appear if you are to hover over the text? If you just want to show less you can just apply this css to the div the text used to be in

        white-space: pre-line;
	display: -webkit-box;
        -webkit-line-clamp: 5; /*Amount of lines you want here*/
	-webkit-box-orient: vertical;
	overflow: hidden;
	text-overflow: ellipsis;
