Missing “continue” button in checkout

Hi, I find an issue with the “Woocommerce Paypal Payments” in the checkout. I tested it with the storefront theme.
Flow:
– add the product to the cart
– on the checkout page don’t fill data
– click pay with PayPal
Result:
– there are errors because required fields aren’t filled
– I can fill required fields, but there isn’t a continue button
– there is only a pay with PayPal button, if I click it I should again process the payment
Expected result:
– there should be a “continue” button and the “pay with PayPal” button should be hidden. I see it works if I reload the checkout page, but it should work without reloading the page because the user doesn’t know what he should do. see my screenshot https://prnt.sc/zeU8JwHKAN48.

As I see, for me, it’s happened on mac when the window is not fullscreen
