Custom roles listed in inventory are not automatically loaded

I'm running debops 2.0.1 (btw thank you all for the efforts and the amazing platform, really appreciated) and I've also updated the playbooks with debops-update. I wrote a simple custom role to install MatterMost and placed it in project/ansible/roles. I listed the role in the inventory among children like [debops_service_mattermost]. If I run `debops service/mattermost -l media` it works fine. If I run `debops -l media` it runs all the playbooks but it does not load the mattermost role. I checked the debops log file and there is no trace of this role being run. Is it supposed to be like this? Is there a way to force custom roles to run on `debops -l media` ? Thank you! Demetri
