Wait for the workflow to complete before continuing option on to the child workflow with assign flexi task creating 2 tasks

Hi,

I have a workflow with lot of Assign Flexi tasks to be send to different groups for approvals with customized Nintex forms. Because of the custom Nintex forms the workflow has grown too big so, I have broken this into smaller chunks.

I have an Assign Flexi task on to the child workflows to send approval notifications. Now the issue is, when I choose the option of "Wait for the workflow to complete before continuing" on to the child workflow the Assign Flexi task action is creating 2 Workflow tasks for each individual user. I need the option "Wait for the workflow to complete before continuing" to be chosen as I would like the parent workflow to proceed only when child workflow is completed.

Nintex Workflow 2013 version is: (3.2.2.10) - English

Nintex Forms 2013 ( 2.10.0.2 ) - Enterprise Edition.

Thanks,

Nirmala
