Intracosmic Blastshot not generating errands automatically

I'm noticing that errands are not generated for the following buildings:

Conveyor loader 
Meteor blaster

I'm making the intracosmic blastshot on a different planetoid, then using the teleporter to transfer them.  It's possible to generate errands on the conveyor loader by selecting another material then deselecting it.  However once some blastshot have been delivered, no new errand is created.  Similar issue with the meteor blaster - it doesn't have any errands.  Deselect intracosmic, reselect it...now there are errands.
