Hi @Sonia_Calero and welcome to the Forum!
If you’re not referring to My TAsks, I would recommend reaching out directly to our support team who will be in a better position to help; in order to speed up investigations, can you make sure to provide them with the following information?
- The URL of the project
- The name of the missing sections
With this information, our team should be able to identify where are these 3 missing sections!
Hope this helps
