WooCommerce Checkout Form not working on desktop

Hello,

This is my first post, so sorry for my mistakes in advance!

I have 2 problems with my WooCommerce Checkout form.

#1 The logos of the different payment methods are too big on desktop, altough small on mobile (on mobile they look good)

#2 The fields to enter the payment data are not showing on desktop. Again, on mobile everything is woring perfectly.

For both problems, here is a screenshot: https://imgur.com/a/puQ3lLt

Thank you in advance for your support!
