Converted to a Discussion.
Could you provide your workflow example so someone answering your question can look in more detail?

Have you assigned the output of the action to the output of the workflow? As far as I can tell, there's no "drag and drop" way to do this, you have to edit the yaml file (in the workflow designer. Consider my workflow that contains a single operation that outputs and publishes date into "outputs" variable:

This is the output of the single action. If I want the output of said action as the output of the workflow itself, I have to assign it to the workflow output in the yaml definition like this:
