Non print files product being sent to dashboard

Hey! Kat from Printful here.
The solution would be to set them as “Ignored” on your Printful profile. You can do so by clicking on Stores > your Woocommerce store > find the product from another provider, click on the three vertical dots next to it > click on Ignore.
That should do the trick! More info about this feature can be seen here – https://help.printful.com/hc/en-us/articles/360014067659-What-happens-if-I-ignore-a-product-.
