Im creating my first listing and i need a GTIN exemption but AMAzon doesn´t give the option to do it, How can i proceed?

Although i get GTIN exemption, i still need to get a GTIN again and again.....i don't know what i can do

Good evening,

I am a new seller and I am trying to submit a couple of items that I want to sell. They are generic and have no barcodes on them so I had to apply for a GTIN Exemption. It appears that it has been approved but when I select the option In the Product Identity section of the listing it is still flagged red and will not allow the listing to be submitted.

Are there any further steps that I need to take in order to submit my product?
