Offset with pagination on custom query

Hey guys, hoping you can help here. I’ve tried several things but nothing seems to work…

So as you can see from my link, theres a top header showing the latest post and the bottom part should show the rest, but its displaying the latest post again.
I’ve inputed a <?php wp_reset_query(); ?> so the top doesn’t conflict with the bottom half. The top half works perfectly tho.

Here is my code for the bottom half:

<?php
					$paged = ( get_query_var( 'paged' ) ) ? get_query_var( 'paged' ) : 1;
					$args = array(
							'posts_per_page' => 10,
							'cat' => '3,4',
							'paged' => $paged
					);
					$custom_query = new WP_Query( $args );
				?>
				<?php if ( $custom_query->have_posts() ) : ?>
				<?php while ( $custom_query->have_posts() ) : $custom_query->the_post(); ?>
	
	<?php $backgroundImg = wp_get_attachment_image_src( get_post_thumbnail_id($post->ID), 'large' );?>

     <?php $class = (empty($class) ? 'class="alternate"' : '');?>
		<div id="bios-posts-single" <?php echo $class; ?>>
		     <a href="<?php the_permalink(); ?>">
		     		<img class="hidden" src="<?php echo $backgroundImg[0]; ?>">
		     		<div class="bios-post-info">
		     			<small>Bio: By <?php the_author(); ?></small>
		     			<h1 class="bios-post-h1"><?php the_title(); ?></h1>
						<? echo '<p class="post-excerpt">' . get_the_excerpt() . '</p>'; ?>
		     			<?php the_date('m-d-Y', '<h2>', '</h2>'); ?>
		     		</div>
		    		<div class="bios-post-img">
		    			<img class="shown" src="<?php echo $backgroundImg[0]; ?>">
					</div>
		     </a>
		</div>
		 <?php endwhile; ?>
				<div class="pagination">
				    <?php 
				        echo paginate_links( array(
				            'base'         => str_replace( 999999999, '%#%', esc_url( get_pagenum_link( 999999999 ) ) ),
				            'total'        => $custom_query->max_num_pages,
				            'current'      => max( 1, get_query_var( 'paged' ) ),
				            'format'       => '?paged=%#%',
				            'show_all'     => false,
				            'type'         => 'plain',
				            'end_size'     => 2,
				            'mid_size'     => 1,
				            'prev_next'    => true,
				            'prev_text'    => sprintf( '<i></i> %1$s', __( '<', 'text-domain' ) ),
				            'next_text'    => sprintf( '%1$s <i></i>', __( '>', 'text-domain' ) ),
				            'add_args'     => false,
				            'add_fragment' => '',
				        ) );
				    ?>
				</div>
	<?php wp_reset_postdata();?>
				
				<?php else : ?>
				    <p><?php _e( 'Sorry, no posts matched your criteria.' ); ?></p>
				<?php endif; ?>
