Hi @jgraup

Yes, the function contains a loop which would run when the posts__in arg is supplied (this is used by ACF):

// array of post ids
137	                // post_parent__in & post_parent__not_in since WP 3.6
138	                foreach (array('post__in', 'post__not_in', 'post_parent__in', 'post_parent__not_in') as $key) {
139	                        $arr = array();
140	                        if (!empty($qv[$key])) {
141	                                // post__in used by the 2 functions below
142	                                // useless to filter them as output is already in the right language and would result in performance loss
143	                                foreach (debug_backtrace() as $trace)
144	                                        if (in_array($trace['function'], array('wp_nav_menu', 'gallery_shortcode')))
145	                                                return;
146	
147	                                foreach ($qv[$key] as $p)
148	                                        $arr[] = ($tr = pll_get_post($p)) ? $tr : $p;
149	
150	                                $qv[$key] = $arr;
151	                        }
152	                }

I’m not sure what the code does exactly, but it looks to modify the id’s.

I would advise that you debug this function by printing out the $qv varible before and after this loop. This will show what has changed:

Thanks
