In this case, the field is not assigned to all plans. So if you want to have it shown, you will need to choose the plan (which the field is assigned to) in plans filter dropdown in Subscriptions Management screen
Yes, like this it work, thank you. But i have another little problem with custom field. I have a field "Note admin" that i dont want to be for the users, this is an admin note. I have uncheck the options in the backend but it appear when i am in the view of the plan in the user management menu. See sceenshots.
