Hi,  
My build is building two different docker images.  
The repo structure is:

Root

- A  
dockerfile
- B  
dockerfile

The config.yml starts with the cache command:

```
- setup_remote_docker:
       docker_layer_caching: true

```

Then I have two steps like:

```
- run:
          name: Build A
          command: docker build -t brand/A:$CIRCLE_BUILD_NUM .
          working_directory: A
- run:
          name: Build B
          command: docker build -t brand/B:$CIRCLE_BUILD_NUM .
          working_directory: B

```

In each docker file I have these steps:

```
COPY package.json .
COPY yarn.lock .

RUN yarn

COPY . .

RUN yarn run build-ci

```

Now if I run the build without any change in code, all docker command use the cache. If I run the build only with changes in directory B, A commands are using the cache but B commands are not (after the change was copied) which is expected.  
The problem is that if I run the build after a change only in directory A, and A commands don’t use the cache, B commands also don’t use the cache although there was no change inside B folder.

Any idea why?  
Thanks
