I fixed this issue on my end by removing an extra do_action function call to registration form tags on our custom form-login.php page. Our form-login.php page was calling both woocommerce_register_form tag and wordpress’ default register_form tag, each on a separate “do_action” function line. I removed wordpress’ default “register_form” tag (do_action( ‘register_form’ )) and left “woocommerce_register_form” (do_action( ‘woocommerce_register_form’ ) and that did the trick.
