Problem with PayPal API

[fenece]

Hello and congratulations on the forum that I have been very useful to set up my first e-commerce site!
I have a small problem to submit: I've set as kind of payment Paypay API and cash on delivery ... the problem is that by default is always kept my PayPal API and will not let me select Cash on Delivery (or any other payments that I've publish) and moreover checkout3 phase (the selection of the method of payment) is skipped and PayPal API is set to defaulf.
If I enable Legacy PayPal also (in addition to the PayPal API and cash on delivery) I see correctly the 3 types of payment (paypal API over all and under cash on delivery and paypal legacy) and I can choose which one to use.
Someone can help me?
Thank you so much and sorry for my english!!!
