[BUG] MAC address changed with the update

[LordMilutin]

Description

Hello.
I have a docker-compose file that has fixed MAC address.
Everything worked flawlessly until recently which I suspect is the new docker update.

Now, when I redeploy the container (docker-compose down && docker-compose up), my fixed MAC address is changed.

I can still see the old one in one part of docker inspect command, but under Networks, it is another one. This used to be the fixed address, however that is not the case anymore.

Is there anything that can be done to preserve that fixed address again under Network, since our licences are based on MAC addresses.

My docker-compse:

services:
 serx:
 image: registry.my.ap/app:release
 container_name: serx
 restart: always
 ports:
 - "9090:9090"
 deploy:
 resources:
 limits:
 memory: 4G
 mac_address: 00:e0:84:35:d0:e8

Running docker inspect serx outputs this, and you can clearly see two MacAddress values, one that I set and one that is randomly generated:
