Duplicate end point error

Hi Xano Team

I am receiving the below error when I try to create put action to update a staff record. I doubled checked the api page to ensure that there are not other end points with the same naming convention.

I am able to create it when using a lowercase c for Contacts, but then it creates a new API grouping, which I don't want.
