Hi there!
I understand your concern. Please note that, generally, we do not provide support for custom CSS. However, as an exception, here is the CSS code to help fix your layout issue:
.woocommerce-checkout .woocommerce-billing-fields-custom button.show-password-input {
display: none !important;
}
If adjusting that does not help, I would recommend contacting your theme provider, as the site layout is controlled by the theme. They will be able to provide you with the proper steps to resolve the issue.
Thank you
