It has been reported by multiple users that the difference between Creator and Contributor is not clear.
Moreover, some users confuse "Creator" with who is creating the record, instead of the publication's author, and as a consequence, use Contributor for the authors of the publication.

While the difference between author and contributor is explained here and here, I think that the most actionable explanation is to clarify that contributors are not added to the citation string in InvenioRDM.

1. Change the Creator label to Author
2. Add a help text to the Contributor to clarify the citation part, so it is easy for users to decide how/where to add authors.
