Subflow not showing executions

[Mary T]

I have created a Flow "A" with subflow "B".  The trigger for "A" is service catalog request.  One of the actions in "B" is to request approval. 

I see "A" triggered and it called "B".  I am able to see the record created in the approval table, but cannot find how to visualize that subflow. 

From the Flow "A" execution, I do not see a way to open the subflow "B" execution. 
When navigating to the subflow "B" and clicking executions, it only shows the records from when i tested it via the designer and not the ones been called from parent flow "A" due to an actual request.

What am I missing?

are you trying to test your sub flow separately ?if yes then it will show into the execution section.
