Is there an issue with adding new items to the fabricator?

Hey all,

I have one mod that adds an item to the fabricator, which seems to work fine, but I just created another new seperate structure mod and no matter what I do it will not show inside the fabricator. The settings are the same as my previous mod bar the folder directory, as one is in crafting and the other is in cooking. Is the fabricator buggy or is there an issue with multiple new items being added to it?

Just to confirm, when I test it in the dev kit it shows perfectly, but on our server nothing will show, even when I build a new fabricator, but my previous mod does.
