I created a simple workflow that has some parallel tasks to be executed.
Refer to the attached image of the workflow for more context.
I execute task 3 and arriving at task 4 I see that task 4 is alive and task 2 is also alive.
The bug for me is that task 2 shouldn't be alive because of the Exclusive gateway.
Tested on 7.3.3 and 7.5.0.
Happens on both.
