Hi!
First, please make sure that the credit card payment option is activated in your paypal account directly, as well as that your account is eligible for this option and doesn't have any restrictions.
Also, the option itself is present in the module only for several countries, such as the USA, Mexico, Brazil, Germany etc. If your country is not on the list, the option won't be present in the module separately.
If this is not your case, I invite you to create a support ticket for us with more details:
