Checkout with Paypal button gone

I just updated and while everything looked like it’s working, after I add items to my cart, then select Checkout, then it used to have the paypal button. This is now replaced with my logo (and clicking it puts me to paypal).

I don’t know how to get rid of my logo and have the default paypal logo instead. I believe this was part of the recent update as it worked fine yesterday.

This is very confusing and I don’t know where to fix it – please help.
