[Plugin: WTI Like Post] How can I get like button to display in grid excerpts?

I am using Post Grid plugin to display image, title and excerpt from my posts in a grid layout.

I need the like button to be available from the excerpt for each post in the grid.

i have put the WTI Like Post “shortcode” in the post-grid/grid-items/layer-content.php file in the loop which populates the grid with the excerpts from each post.

elseif($item_key=='excerpt'){
			$html.='<div class="element '.$item_key.'" style="'.$item_info['css'].'" >';
				$html.= wp_trim_words(get_the_excerpt(), $char_limit,'');

				$html.= GetWtiLikePost();

 			$html.='</div>';

			}

This makes all of the like buttons appear on the top left, outside of the grid! See this image. Can someone offer some advice as to why this is happening?

thanks
