Bulk Editing Not Working

Bulk Editing Not Working

Hello, 

I am having an issue with the Zoho Commerce Bulk Edit Procedure. 

My goal is to mark all my items as "Not Visible in Store" by editing the CSV column from YES to NO. However, when i try to reimport the CSV the way the instructions tell me to, i get an error message that tells me all of my products already exist, and none of the records update. 

Has anyone else faced this issue? If so, how did you get around it?

Thank you!
