Products In Database but not in Backoffice

[Mitchell Creative]

As my title says, guys, my products are linked to my database with Datalink which manages my stock and names of products. My products are syncing fine and quantities update but a few of my products won't show on my back office even though they are showing in the database.

Please see the attached images for our top product ID's as you can see they can only go to the 11xxx number. whereas our product in the database is sitting at 12408.
