I’m having an issue with a job that shouldn’t be there. I’ve workflows in my configuration and this job is trying to run default build task generating a false-negative in my PR checks.

Job: https://circleci.com/gh/gcoguiec/vuex/136#config/containers/0
PR: https://github.com/vuejs/vuex/pull/1372

The ten other “legit” jobs are running fine, though.
I’m pretty sure that 11th job shouldn’t be there.
