Wrong user role via API

Hi, I have some custom role on woocommerce and I have assigned it to customer (es: https://imgur.com/a/yQOtD1o)

If I check this user via API, the displayed role is wrong https://imgur.com/a/UtbnVSI

The correct slug for this role is this -> https://imgur.com/a/uN8oMMW

Please help me, thanks
