mismatch between published JSON schema for bitbucket-pipelines.yml and bitbucket pipelines validator

[Max DeCurtins]

This is driving me nuts. I'm using WebStorm as my IDE, and when editing my bitbucket-pipelines.yml file, it is giving me a schema validation error on the following block (generic example):

pipelines:
  branches:
    master:
      - stage:
          name: My Stage
          steps:
            - step:
                name: My Step

It says that the property "stage" is not allowed. I have WebStorm pointing directly to https://api.bitbucket.org/schemas/pipelines-configuration for this file.

However, if I copy/paste the bitbucket-pipelines.yml file in its entirety to https://bitbucket.org/product/pipelines/validator , it says my configuration is valid.

What gives?? This is driving me crazy.
