Cannot specify different plan names in child job set parallel plan run steps when running under a parent job set.

We have a business requirement to run planning collection and there after 3 Supply plans. Supply plans should be run in parallel to expediate the process. We want to use a parent job set to run the collection in step1 and run a child job set in step2. The child job set will run 3 supply plans in parallel. When we are running the child job set independently, it allows us to select 3 different plans to run simultaneously.
However, while running the parent job set, we are not able to select different plans. The plan selected for the first “Batch Run Plan” is defaulted in subsequent 2 steps also. If we change plan name in second or third step, it changes the plan name for the other two steps also.
Thus we are not able to run 3 plans simultaneously through the parent job set.
Detailed screenshots of Job sets are attached.

Note:- We have already set "enableDuplicateJobWithParamTaskflow = true"
