Traefik in docker with Multiple domains and SSL

I'm struggling to understand how to set Traefik up for multiple TLDs within docker and have it pull their certs. Here's my docker-compose.yml:

version: '3'

services:
traefik:
image: traefik:latest
container_name: traefik
restart: unless-stopped
security_opt:
- no-new-privileges:true
networks:
- proxy
ports:
- 80:80
- 443:443
environment:
- CF_API_EMAIL=
- CF_API_KEY=

  - /etc/localtime:/etc/localtime:ro
  - /var/run/docker.sock:/var/run/docker.sock:ro
  - /root/traefik/data/traefik.yml:/traefik.yml:ro
  - /root/traefik/data/acme.json:/acme.json
  - /root/traefik/data/config.yml:/config.yml:ro
labels:
  - "traefik.enable=true"
  - "traefik.http.routers.traefik.entrypoints=http"
  - "traefik.http.routers.traefik.rule=Host(`traefik-dashboard.myfirstdomain.com`,`myseconddomain.com`)"
  - "traefik.http.middlewares.traefik-auth.basicauth.users=user:<hashedKey>"
  - "traefik.http.middlewares.traefik-https-redirect.redirectscheme.scheme=https"
  - "traefik.http.middlewares.sslheader.headers.customrequestheaders.X-Forwarded-Proto=https"
  - "traefik.http.routers.traefik.middlewares=traefik-https-redirect"
  - "traefik.http.routers.traefik-secure.entrypoints=https"
  - "traefik.http.routers.traefik-secure.rule=Host(`traefik-dashboard.myfirstdomain.com`)"
  - "traefik.http.routers.traefik-secure.middlewares=traefik-auth"
  - "traefik.http.routers.traefik-secure.tls=true"
  - "traefik.http.routers.traefik-secure.tls.certresolver=cloudflare"
  - "traefik.http.routers.traefik-secure.tls.domains[0].main=local.myfirstdomain.com"
  - "traefik.http.routers.traefik-secure.tls.domains[0].sans=*.local.myfirstdomain.com"
  - "traefik.http.routers.traefik-secure.tls.domains[1].main=myseconddomain.com"
  - "traefik.http.routers.traefik-secure.tls.domains[1].sans=*.myseconddomain.com"
  - "traefik.http.routers.traefik-secure.service=api@internal"

networks:
proxy:
external: true

Can anyone say what I might be doing wrong?

Right now it's pulling the certs for the first domain, but not the second.
