Cannot import CSV into Name field

[cosmo (Cosmo Scharf)]

When I import a CSV to my CMS, I cannot select the name field. I created another name field to test if that would work, and it does, which is odd. The text is plain text. Any help appreciated!

Without seeing an example of the CSV and the collection in the designer you are on your own.
