Hi All,
I have a Calendar which had a Designer form for Both Edit And new Item, Now I want to Create a new Nintex form for the same, However the List shows Designer form instead of Nintex form even after the Nintex Form is published.
As you can see in this image the workflow is published and is current version 3.


Should I do any change in content type or any other region befor publishing the Form for Calendar?
Thanks for your help.
