I have two workflows I published that were part of one specific collection. I removed them from that collection with the intent of adding them to a different collection. But when I go to the collection and click on Workflows => Add and start typing in the name of either of the workflows, they do not show up. I also have schedules for the workflows; I was able to remove the schedules from the first collection and then add them to the second. But I can't add the workflows to the second collection; I can't even add them back into the first collection that I had removed them from. Any ideas on what is going on?
