compose.yaml seems to have to many lines

[DarkDau]

Hello, I have discovered docker-autocompose. It would very helpful!
Which makes me wonder. when I use it to query a container, also like this:
"docker run --rm -v /var/run/docker.sock:/var/run/docker.sock red5d/docker-autocompose wikijs >docker-compose.yaml
WARNING: IPv4 forwarding is disabled. Networking will not work."
so far so good.

the compose.yaml is written, then when i test it with docker-compose config i get "docker-compose config.
ERROR: Invalid interpolation format for "environment" option in service "wikijs": "PS1=$(whoami)@$(hostname):$(pwd)$ ""
Error messages, even if I delete the PS1 entry,
there is an error:"
docker-compose config

Traceback (most recent call last):

File "/usr/lib/python3/dist-packages/compose/cli/command.py", line 91, in get_config_from_options
return config.load(
... many more entries

The generated compose.yaml looks good at the beginning.
When I remove the bunch of **label: Entries**, the config check is ok.
So my question is **about label:** why is it, can one disable this? 
**if I delete all entries for label: then there is no further error, so I use it as workaroud**
