How to set timeout parameters on docker-compose

OS version: Ubuntu 16.04
Docker version 19.03
redash Image: redash/redash:6.0.0.b8537

I woud set two parameters below intending to detect timeout queries.

REDASH_ADHOC_QUERY_TIME_LIMIT
REDASH_JOB_EXPIRY_TIME

Environment Variables Settings

But timeout does not work well.
After I configed docker-compose.yml, done down/up docker-compose. Through docker inspect, I can see the variables of two parameters in redash_server container.

Do I misunderstand how to set redash variables on docker enviroment?

about the variable of LOG_LEVEL, I also could not work well.

sincerely, I hope your advice.
