Why aren't my items transferring to the Shop app?

[keith4031]

Discovered that most of my items would not transfer over to Shop. When trying to edit the product I went into the publishing sections of the ones that transfered over and those that didnt. The ones that were listed had Shop listed in where Facebook, Instagram and tiktok, but the ones that didn't did not include Shop in that section. And I cant find a way to correct it
