@lpb do you know why it shows “Created by Brian” though?
When I add an Asana-created custom field in one of my projects it still says “Created by Asana”
And actually upon checking further also in my org another “priority” field appears which is set up exactly the same way but shows created by me although it is an Asana-created field.
And both have the Asana icon, just slightly different description
And both are added to the org library.
I have now also found this post where somebody reported similar, but here it is understandable due to various languages.
And I have also found this post. which seems to be a bit similar to this issue?
