nginx: [warn] protocol options redefined

I’m updated nginx to 1.23.4, and nginx -t start showing warnings:

nginx: [warn] protocol options redefined for 0.0.0.0:443 in /etc/nginx/sites-enabled/beta:5
nginx: [warn] protocol options redefined for [::]:443 in /etc/nginx/sites-enabled/default:28
nginx: [warn] protocol options redefined for [::]:443 in /etc/nginx/sites-enabled/grafana:5

These lines are

    listen 443 ssl;
    listen [::]:443 ssl;
# sometimes:
#    listen 443 ssl;
#    listen [::]:443;
# I'm now know - some inconsistency, fixed

But after tweaking and adding http2 there were more warnings.
