Many to many relation for the same table

[DroidTeo]

Hello all! 

I have a table users, each user can cover different position: 

• team leader
• coordinator
• normal user

and a coordinator can be manager of 1 or N normal users
and a team leader can manager 1 or N coordinator

So, I have this users table wihtin the following columns: user type, team leaders and coordinators.

Inside appSheet I configured the columns as below: 

But it doesn't work.. Inside the application I have only the label but not input field.. 
How can I do this? 

Thanks a lot!
