I just solved it myself:
Because of the animation that happens on the removal of a repeater row, there is a 250ms delay before the values are removed.
by using .on('remove', function()) from jquery-ui the problem is gone.
here is my working code:
$j("." + currenttab + i).on("remove", function () {
calculate_subtotal(currenttab);
})
Thank you for your help!
This is how I fixed the problem:
I used the init hook to load in acf_form_head() like so:
function form_head() {
if (!is_admin()) {
acf_form_head();
}
}
add_action('init', 'form_head');
At first I used the init hook without the is_admin check, this caused that acf_form_head to load twice/post twice.
The solution is to use the init hook with is_admin() to prevent it loading twice.
