Replica not working as before in multiple Compose files

Description

I've been using multiple Compose files to suppress some services and run it locally in dev environment .

Steps to reproduce the issue:

docker stack deploy -c stack.yaml -c stack.dev.yaml test

https://gist.github.com/leesei/aaa22b2ea191c2ef313096622359c7e9

Describe the results you received:

2 instances of caddy service, 2 instances of mongo service

Describe the results you expected:

0 instances of caddy service, 2 instances of mongo service

Additional information you deem important (e.g. issue happens only occasionally):

It used to work before. In recent release (maybe a month or so) this was not working anymore. It works if I remove the replica setting in the base stack.yaml but I intended it to be my production config. I would like to see if this is the expected behavior, that the base yaml should not contain replica setting.
