Dear Micaela,
With a Basic plan, you are able to configure 10 different payment methods - you probably configured a payment method like credit card multiple times, you do not need to do this. One configuration is enough to then configure multiple connectors such as MasterCard, VISA, AMEX and so on.
If you would like someone from support to have a look at your configuration, please get in touch with us directly with your Space ID so we can have a look. Looking forward to hearing from you at info@wallee.com.
Sincerely,
Dewi
