Yes, I can see all the payment methods when disabling SimpleCheckout. But i just figured it out. This happened when updating a site from NopCommerce 3.8 to 3.9. When installing the SimpleCheckout plugin for 3.9 none of the payment methods were visible. But when i logged out from the admin user and tried other users or when i was logged out, I could see the payment methods. I ended up deleting the admin user from the database and created a new user with admin privileges. I then logged in with that user and the payment methods was now visible. I have no idea why this happened but it works fine now. Could be helpful to others maybe that this may happen when upgrading from 3.8 to 3.9 with existing admin users from 3.8 db.
