@Mauricio_Arias I don’t think it’s possible to delete them by yourself. You can contact Qualtrics for the option of delete them. Or just create you own usertype and ignore those defaults that you don't care about.

@Mauricio_Arias unfortunately these are standard and not aware of any documentation to explain the use of each one.  Qualtrics documentation talk about very few of these; however they have many more loaded in than are explained. 

Deleting them has not been an option when I have engaged support around this previously looking to clean up the volume of roles we had. We had almost 100 user roles; then realised the bulk of these and all that were unused were Qualtrics default options we can’t adjust. However as per @dxconnamnguyen comment; hopefully they can do this for you if you reach out.

We use our own roles; and you adjust your permissions as needed.  Brand Admin is the only Qualtrics default role we utilise.  

Thank you so much for your advice. I touched in with Support, and They can confirm that each of these is a Qualtrics Global Type (i.e., they are built into the platform), and it is not possible to delete global types like those above.The Product Management has shared internally that they plan to phase them out in a future update to the platform. 

@Mauricio_Arias thanks for the update on how you went, saves me following up potential deletion again on my end.
