Guest Checkout and Login Required settings

Hello,

I have been using this plugins many years. I want to know When I checkout from the website it is asking me for compulsory login in the paypal account in order to purchase the product which is not good.

I tried wiht the paypal settings make the account optional ON and still it is asking the same thing here do you have any solution ?

When Client trying from Europe it is showing the compulsory login where here in india it is not showing the compulsory login option.

Please guide me on this.
