displaying choice in django admin

im making a reservation app, i want one of the ways to see the data being in the admin panel but right now i can see everything except for the time, i think it is because its a choice field and in the admin it appears like it wasnt chosen.

models.py

class Reservation(models.Model):    name = models.CharField(max_length=50)    people = models.IntegerField()    date = models.DateField()    time_choice = (        (times_available[0], times_available[0]),        (times_available[1], times_available[1]),        (times_available[2], times_available[2]),        (times_available[3], times_available[3]),        (times_available[4], times_available[4]),        (times_available[5], times_available[5]),        (times_available[6], times_available[6])    )    time = models.CharField(        max_length= 7,        blank= True,        null= True,        choices= time_choice    )    phone = models.IntegerField()    def __str__(self):        return self.name

views.py

def reservar_mesa(request):    reserve_form = FormReservarMesa()    if request.method == 'POST':        reserve_form = FormReservarMesa(request.POST)        if reserve_form.is_valid():            reserve_form.save()            reserve_form = FormReservarMesa()            return HttpResponseRedirect("/home/")    context = {'form' : reserve_form}    return render(request, 'reservas.html', context)

my admin.py is the deafault.i checked and the value is being stored in the database
