PayU plugin is not redirecting to Payment Options page

Hi,

I am using PayU plugin on my website, but when I click on Pay Now button – this plugin redirects me to …/cards page:

Here, I have to click on the “Back” button on the top left corner to open the “Payment Options” page (…/paymentoptions). To select a different payment method.

So, why is it not redirecting me to the “Payment Options” page by default?

Thank you.
