Hello,

Please go to tower/includes/codeless-slider/codeless_slider.php and find these lines:

if(!empty($cl_redata['slide_button1']))
								$output .= '<a class="btn-bt '.esc_attr($cl_redata['overall_button_style'][0]).' '.esc_attr($cl_redata['slide_button1_style']).'" href="'.esc_url($cl_redata['slide_button1_link']).'"><span>'.$cl_redata['slide_button1'].'</span><i class="moon-arrow-right-5"></i></a>';
							if(!empty($cl_redata['slide_button2']))
								$output .= '<a class="btn-bt '.esc_attr($cl_redata['overall_button_style'][0]).' '.esc_attr($cl_redata['slide_button2_style']).'" href="'.esc_url($cl_redata['slide_button2_link']).'"><span>'.$cl_redata['slide_button2'].'</span><i class="moon-arrow-right-5"></i></a>';

Replace with these:

if(!empty($cl_redata['slide_button1']))
								$output .= '<a class="btn-bt '.esc_attr($cl_redata['overall_button_style'][0]).' '.esc_attr($cl_redata['slide_button1_style']).'" target="_blank" href="'.esc_url($cl_redata['slide_button1_link']).'"><span>'.$cl_redata['slide_button1'].'</span><i class="moon-arrow-right-5"></i></a>';
							if(!empty($cl_redata['slide_button2']))
								$output .= '<a class="btn-bt '.esc_attr($cl_redata['overall_button_style'][0]).' '.esc_attr($cl_redata['slide_button2_style']).'" target="_blank" href="'.esc_url($cl_redata['slide_button2_link']).'"><span>'.$cl_redata['slide_button2'].'</span><i class="moon-arrow-right-5"></i></a>';

Save changes.

Best regards!
