Hi Noelia,

Thank you for contacting WPClever Support Forum. We’ve received your ticket. 

First, please make sure you have used the auto-price instead of manually entering a price in the General tab since that price is a fixed price. 

Next, the description is not enough for us to find the cause of the problem. Please provide us with some screenshots of back-end settings and a link to your published product for checking? 

After receiving your information, I'll proceed to the next step. 

Best regards.
