Hi @rafikhassan, thanks for leaving a review.
The new Credit Card design in our latest version has come from updating to the newest PayPal Javascript SDK framework and unfortunately, we cannot change the design of these buttons within our plugin.
One way to bring back the old credit card design is to use the following filter to switch back to use the deprecated checkout.js integration:
add_filter( 'woocommerce_paypal_express_checkout_use_legacy_checkout_js', '__return_true' );
Keep in mind this javascript is no longer being updated or maintained by PayPal. More information here: https://developer.paypal.com/docs/archive/checkout/
