do not want to display fieldsets django

There is such a model

class Forwarder(models.Model): name = models.CharField('Название',max_length=120, null=True, blank=True) link = models.CharField(max_length=120, null=True, blank=True) phone = models.CharField(max_length=120, null=True, blank=True) APPROVAL_CHOICES = ( ('1', 'Viber'), ('2', 'Telegram'), ) messanger = models.CharField('Мессенджер', max_length=100, default='Выберите мессенджер', blank=True, choices=APPROVAL_CHOICES) channel_id = models.CharField('ID канала', max_length=120, null=True, blank=True) users = models.ManyToManyField (ViberUser, blank=True, verbose_name='Viber пользователи') proj = models.ManyToManyField(Project,blank=True, related_name='tg_projects' ,verbose_name='Проекты') created_date = models.DateTimeField('Дата создания',auto_now_add=False, auto_now=False,null=True, blank=True) status = models.BooleanField(('Активирован'),default=True) comments = models.TextField('Комментарии',null=True, blank=True) 

In the admin.py file I try to do fieldsets

 class ForwarderAdmin(admin.ModelAdmin): list_display_links = ('name',) list_display = ('status', 'icon', 'name', 'l', 'sitelink', 'created_date', 'd7', 'd30', 'd90') search_fields = ['name'] fieldsets = ( ('Информация о пересыльщике', {'fields': ('name', 'phone', 'messanger')}), ('Проект', {'fields': ('proj')}), ('Телеграм канал', {'fields': ('link', 'channel_id')}), ('Viber бот', {'fields': ('users', )}), ('Доп. поля', {'fields': ('created_date', 'status', 'comments')}), ) 

I get an error -

If I remove line 2 from fieldsets

 ('Проект', {'fields': ('proj')}), 

Then everything will be fine and work. Errors in the crooked writing can not be, because copied the names of the main model
