"Move to Another Workflow" Process shows no trigger

"Move to Another Workflow" Process shows no trigger

I have a workflow (A) that when finished leads to workflow B. The "move to another workflow" at the end of workflow A shows no other workflows to move to even though my workflow B begins with an open trigger.

I have the API key for the open trigger but it says it is not needed to move between workflows.

What am I missing here?
