Oh man, we really should have explained that better, it seems ^^'
The "inventory" on the bottom of your screen shows the 7 sharks that you've created, all of those are "correct" orders, since you made them for the shop.
Every order that you did not build in the builder is "faulty", (aka. the ones with the snake). All of those can be in queue and "produced" but since you technically don't have the snake part in the builder, they can not be sent.
Sometimes H-AI builds them by accident, those you can repair.
The snake was more of a way to mark orders as not fitting your catalog, if that makes sense!
Thank you for the detailed response and the kind feedback, it's super helpful to read :>
