Hi Peter,
May I know how you added it? You have to edit the existing code you have shown in your screenshot and just add the slider in front of the sharing code. Example, replace this part
echo do_shortcode('[share
with this part
echo do_shortcode('[rev_slider alias="TEST"][share
And not by replacing the entire code. But if you just accidentally added it in the wrong place then you can fix it by removing it from the place where you added it. And please don’t provide your codes and credentials in a screenshot in the future, a text copy is more recommended that will also serve as your back-up 
Here is the code for the sharing code that I copied from your screenshot.
add_action( 'x_before_the_content_end', 'x_print_social', 999);
function x_print_social() {
if ( is_singular('post') ) {
echo do_shortcode('[share title="Share the Magick!" facebook="true" google_plus="true" linkedin="true" pinterest="true" reddit="true"]');
echo '<p style="text-align: center;"><a href="https://intothemythica.com/subscribe//">LIKE THIS ARTICLE? WANT TO HELP CHANGE THE WORLD? CLICK TO JOIN THE MYTHICA!</a>';
}
}
And add this code for the category related slider, please ignore the previous instructions 
add_action( 'x_before_the_content_end', 'x_post_category_slider', 998);
function x_post_category_slider () {
if ( is_singular('post') ) {
$category = get_the_category( get_the_ID() )
$slider = "";
if ( count( $category ) > 0 ) {
switch ( $category[0]->term_id ) {
case 223: $slider = '[rev_slider alias="ftq-yeshualucis"]'; break;
case 228: $slider = '[rev_slider alias="FTQ-peterfae"]'; break;
}
echo do_shortcode( $slider );
}
}
}
Again, you’ll have to enhance that code to achieve your main goal. Example, let’s say the category From the Quest - Yeshua Lucis
has an ID of 223, then this is the line responsible for that
case 223: $slider = '[rev_slider alias="ftq-yeshualucis"]'; break;
Or category From the Quest of Peter Fae
has an ID of 228, then the line is
case 228: $slider = '[rev_slider alias="FTQ-peterfae"]'; break;
The ID is just an assumption, you’ll have to check your category IDs manually, please check this https://theme.co/apex/forum/t/setup-how-to-locate-category-ids/60
Again those two lines are just sample, you have to enhance it by changing the category ID, slider shortcode, and even adding more lines. And this should serve as snippet and an idea and we don’t cover code maintenance, I recommend contacting a developer of maintaining this code.
Thanks!
