Useless "No workflow" pipeline created when there's no workflow

In my config.yml I have a single workflow that is triggered only on push to ‘dev’ branch. When I push to any other branch except ‘dev’ CircleCI creates a pipeline with status ‘CREATED’ and workflow shows ‘No workflow’. This looks like useless spam. Can I disable it?

Same here, I only want to build on master for release build right now and it creates this for any other branch I create. build has master only designated.

Anything new about this issue? Where you able to resolve it?
