Invalid email address on Stripe Checkout

hi, trying to do the test with Stripe in Test mode.
when entering test card details it’s gives me an error: Invalid email address.
no need to say, that there is no field for the email address on the page. So I just doubt what it’s talking about.
When trying to Proceed to Pay again – it’s give the error
“Error: Missing Stripe token. Please try again.”
so, I do not understand how to make it working – I have been setting up other Stripe accounts with WooCommerce and other plugins, but never had this problem before.

Please assist.
Regrds,
Kos
