If you have the chatterbox on you or in stash you cannot craft another. It is silly but that is how it works. If you are trying to use it for compo ents transfer the one you have to an alt (cannot remain in stash) then you can craft another and break down and repeat as many times as you wish.
If this is the first craft then it is probably a bug, not sure what would be the reason for that
If tou have the chatterbox in your inventory or claims tou CANT get the parts until you destroy one or move it to another character.
Have tou tried talking to the lady right by the crafting bench? She might have the blueprint to buy the you might be able to make it.
When tu10 came out i have to go back to bank headquarters to find the blue prints again. Even though before tu10 i made a few dozen chatterbox's.
Logging out and back in might fix it. I know there sometimes is a lag between getting the blueprint and being able to use them
