From Conveyor process is not accepting 2nd assembly.

Hi! I have been having issues with a from conveyor process. The process is transporting in an assembly and transporting it out piece by piece as desired, but as soon as the first assembly is processed the conveyor does not transport in the next assembly even though it is queued. Has anyone else had this issue or have any suggestions?

You might still have an empty assembly product in there unless you delete it.
