leap cli doesn't recognize couch.master mode

i'm trying to use couch in "master" mode. however, compiling ends up in "mirror" mode:

--- pixelated-platform-environments/pixelated-project.org ‹couch16* MD⁇› » cat nodes/*
{
  "ip_address": "10.5.5.2",
  "services": [
    "couchdb",
    "monitor",
    "mx",
    "soledad",
    "webapp"
  ],
  "couch.master": true
}

--- pixelated-platform-environments/pixelated-project.org ‹couch16* MD⁇› » leap compile 

--- pixelated-platform-environments/pixelated-project.org ‹couch16* MD⁇› » grep mode hiera/couch16.yaml 
  mode: mirror
