Blocked System managed

[Anonymous]

I'm trying to import my very first list of contacts from a CSV file. 

I've renamed one of the column headers to 'Updated At' to match one of the Marketo Fields but I keep getting this "Blocked (System managed)" message in the notes section and I can't click forward to the next page.  

Any help would be appreciate. Thanks!

A system managed field is one that you cannot write/toupdate. You will need to create a custom field to write your "updated at" information.

That did it. Thanks Cheryl!
