"GreenWay" and "ZSE Drive" appears in both operators and brands

[LaoshuBaby]

In data submitted a few days ago, those 2 brand (or operator?) was upload as brands, but they already exist in our data. I open this issue
on the purpose to ensure it should be which one. This is similar situation about #6909.

⚠️   Warning - matchIndex errors:
----------------------------------------------------------------------
  `key/value/name` occurs multiple times in the match index.
  To resolve these, make sure the key/value/name does not appear in multiple trees
    (e.g. `amenity/post_office/ups` should not be both a "brand" and an "operator"

@RickeyRichards , could you give some advice about this choice? Since you're the local mapper adding them. Hopefully this isn't particularly tricky (If so, which community should we ask for help?).
