Email configuration doesn't apply

Hello! I'm using the docker composer from open-core.

Initially I configured it without email support, but now I need to add those configurations.

When I try to send a test email I get the error: Notification has email recipients and is triggered, but email transport is not configured. Email transport is not enabled in server configuration file!

I've tried adding the following to the .env file:

GRAYLOG_TRANSPORT_EMAIL_PROTOCOL="smtp"
GRAYLOG_TRANSPORT_EMAIL_WEB_INTERFACE_URL="https://192.168.1.1/"
GRAYLOG_TRANSPORT_EMAIL_HOSTNAME="smtp.example.com"
GRAYLOG_TRANSPORT_EMAIL_ENABLED="true"
GRAYLOG_TRANSPORT_EMAIL_PORT="587"
GRAYLOG_TRANSPORT_EMAIL_USE_AUTH="true"
GRAYLOG_TRANSPORT_EMAIL_AUTH_USERNAME="notification@example.com"
GRAYLOG_TRANSPORT_EMAIL_AUTH_PASSWORD="password"
GRAYLOG_TRANSPORT_EMAIL_USE_TLS="true"
GRAYLOG_TRANSPORT_EMAIL_USE_SSL="false"
GRAYLOG_TRANSPORT_FROM_EMAIL="notification@example.com"
GRAYLOG_TRANSPORT_SUBJECT_PREFIX="[Graylog-1]"

I also tried adding these to the docker-compose.yml to the graylog service without success.

Here's my docker-compose file:

Just tested again after updating to 5.2.3 with this and it worked
