WooCommerce Checkout page not working on second language

I recently have updated TranslatePress. Since that, the checkout page is not working any more if the second language is selected (in my case english, german is default).

It is not possible to select a payment target (PayPal Express and PayPal Standard installed).

Note, I disabled translation on the page for now.

The page I need help with: [log in to see the link]
