You should use a single acf/save_post filter with a priority > 10.

The way you are doing it you are updating the post 3 times instead of once.

Also, with a priority of 10, your filters may or may not be running before ACF actually saves the values. When dealing with ACF you should almost always use a priority > 10 unless you actually want to do something before ACF saves values. If that’s the case then you should always use a priority of < 10.

I’m actually surprised that you’re not causing an infinite loop since this call wp_update_post( $postdata ); should be triggering ACF to re-save the values and then call your function again.

You need to remove your filters before updating the post and read them after updating the posts.

remove_filter($hook, $callback, $priority);
wp_update_post($postdata);
add_filter($hook, $callback, $priority, $accepted_args);
