Date Appearing Outside of the Main Body in Template

hi,

I want to be able to add a snippet that would appear above the body of my post when I edit a post and add content to an older post. This snippet would in effect say:

‘Last updated on April 19th 2019’. (or whatever date you edited it on).

I’m doing this because its not good practice to remove dates from a post or edit the original publish date. This is a good workaround.

However, the problem is when I add the code to my child functions.php it works okay, but, it appears on the homepage (it should not) it throws the date and words outside of the body to the left of the template body. See screenshot.

Here is the code:

function wpb_last_updated_date( $content ) {
$u_time = get_the_time('U'); 
$u_modified_time = get_the_modified_time('U'); 
if ($u_modified_time >= $u_time + 86400) { 
$updated_date = get_the_modified_time('F jS, Y');
$updated_time = get_the_modified_time('h:i a'); 
$custom_content .= '<p class="last-updated">Last updated on '. $updated_date . ' at '. $updated_time .'</p>';  
} 
 
    $custom_content .= $content;
    return $custom_content;
}
add_filter( 'the_content', 'wpb_last_updated_date' );

The date appears correctly everywhere else and as intended to be. It should NOT be appearing on the homepage. BTW it works outside of this template quite well, so I believe this is a conflict somewhere with this.

Here is where I found the original article that references this code:
