Error - Identifier fields (Task Name) are blank. Please fill in the fields

Hi There,

I am trying to essentially duplicate a project (Project A) with all it’s assets to create a new project (Project B) as a sort of project template. When I try to import the csv asset list I export from Project A into Project B I get an error that identifier fields are blank, although I can see data there.

Any ideas how to fix or remedy this problem?
