Django context processor being called twice per request

I've found only one topic like this and not a single answer in there seems to work.
I have two context processors:

def cart_view(request):
try:
cart_id = request.session['cart_id']
cart = Cart.objects.get(id=cart_id)
request.session['total'] = cart.items.count()
print('OLD CART USED')
except:
cart = Cart()
cart.save()
cart_id = cart.id
request.session['cart_id'] = cart_id
cart = Cart.objects.get(id=cart_id)
print('NEW CART CREATED')
return 'cart':cart

# dropdown menu categories to every page
def categories(request):
print('CATEGORIES CONTEXT PROCCESOR')
categories = Category.objects.all()
return 'dropdown_categories':categories


Settings:

'context_processors': [
'django.template.context_processors.debug',
'django.template.context_processors.request',
'django.contrib.auth.context_processors.auth',
'django.contrib.messages.context_processors.messages',
'django.template.context_processors.media',
'shopping.views.cart_view',
'shopping.views.categories',
]


Via those print statements I'm able to see that each one of those CP being executed twice per request, although I'm rendering just base.html. What may be the problem?

base.html

import traceback; traceback.print_stack() gives this two times:

import traceback; traceback.print_stack()

P.S. I know that I'm querying the DB every time I use CP, I'll add caching later.

Cosole log(that's one page load):

OLD CART USED
CATEGORIES CONTEXT PROCCESOR
[30/Aug/2018 18:56:13] "GET / HTTP/1.1" 200 2651
OLD CART USED
CATEGORIES CONTEXT PROCCESOR
[30/Aug/2018 18:56:13] "GET / HTTP/1.1" 200 2651


View:

class HomePageView(TemplateView):
template_name = 'base.html'


Project URLs:

urlpatterns = [re_path(r'^',include('shopping.urls',namespace='shop'))]


App's URLs:

urlpatterns = [re_path(r'^$',views.HomePageView.as_view(),name='home')]


import traceback; traceback.print_stack()

Well, I don't what magic is this but the issue of getting two requests per page load had something to do with this line of code in my base.html:

base.html

<img src="#" width="30" height="30" class="d-inline-block align-top" alt="">


As soon as I deleted it, everything started to work normaly...
