Django won't set HttpOnly for csrftoken cookie

Question

In my Django's settings.py I have

SESSION_COOKIE_HTTPONLY = True
SECURE_CONTENT_TYPE_NOSNIFF = True
SECURE_BROWSER_XSS_FILTER = True
X_FRAME_OPTIONS = 'DENY'
SESSION_COOKIE_SECURE = True
CSRF_COOKIE_SECURE = True
SECURE_SSL_REDIRECT = True
SECURE_HSTS_SECONDS = 15768000
SECURE_HSTS_INCLUDE_SUBDOMAINS = True
SECURE_HSTS_PRELOAD = True
SESSION_COOKIE_AGE = 2 * 24 * 3600

However https://detectify.com has found that this flag isn't set for csrftoken cookie. I checked what Chrome tells about the cookie, and if I understand correctly, the empty HTTP column confirms that the two cookies are not HTTP-only:

Also, if I do document.cookie in chrome's console, the csrftoken value is shown.

I wonder why this could be the case. I have Django running on uwsgi and nginx. The nginx configuration is as follows, and the site in question is https://rodichi.net:

server {
    listen 443 ssl http2 default_server;
    server_name rodichi.net;

    ssl_certificate /etc/letsencrypt/live/rodichi.net/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/rodichi.net/privkey.pem;
    ssl_dhparam /etc/ssl/certs/dhparam.pem;
    ssl_protocols TLSv1.1 TLSv1.2;
    ssl_prefer_server_ciphers on;
    ssl_ciphers "EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH";
    ssl_ecdh_curve secp384r1;
    ssl_session_cache shared:SSL:10m;
    ssl_session_tickets off;
    ssl_stapling on;
    ssl_stapling_verify on;
    charset     utf-8;

    ... # location settings follow here
