If it is a VM traffic there is no need for you to create another TCP/IP stack .. the second TCP IP stack can be removed. not required.
A 2nd TCP IP stack can be used in cases where you want a different gateway for the vmkernel network.. other than the already existing.
I am not sure if there is any link to the 2nd Switch and the 2nd TCP/IP stack.
If you could remove the 2nd vSwitch also and recreate..
