I don’t know for sure, I think it may have something to do with this part of the code

// find the position of $post_id within $value2 so we can remove it
$pos = array_search($post_id, $value2);

// remove
unset( $value2[$pos] );

Maybe the value you’re getting for $pos is somehow incorrect or somehow does not translate to the correct index, but I can’t say for sure.

Generally, when I’m removing things from an array I build a new array rather than manipulate the existing array and it saves me a lot of headaches.

$new_array = array();
foreach ($old_array as $value) {
  if (/*condition to keep value*/) {
    $new_array[] = $value;
  }
}
$old_array = $new_array;
