1.7 manifest: Localization not working

[xavisegura]

1.7 localization in manifest not working as expected:

• Manifest:
  "$schema": "https://developer.microsoft.com/json-schemas/teams/v1.7/MicrosoftTeams.schema.json",
  "manifestVersion": "1.7",
  "version": "1.0.12",
  "id": "69bac8e5-774e-41fa-90c6-59056ddf0c6f",
  "packageName": "com.kpmg.find",
  "localizationInfo": {
  "defaultLanguageTag": "en",
  "additionalLanguages": [
  {
  "languageTag": "de",
  "file": "de.json"
  }
  ]
  },...
  "name": {
  "short": "KPMG Find",
  "full": "KPMG Find Application"
  },
  "description": {
  "short": "test1",
  "full": "test2"
  },...

• de.json:
  {
  "$schema": "https://developer.microsoft.com/json-schemas/teams/v1.7/MicrosoftTeams.Localization.schema.json",
  "name.short": "test3",
  "name.full": "test4",
  "description.short": "test5",
  "description.full": "test6",
  "staticTabs[0].name": "test7"
  }

When loading the app with MS Teams configured in German:

The displayed description is always test1, test2, so short and full description properties specified in manifest.json, and not test5 and test6, specified in de.json file.

Attached the complete manifest. Thanks in advanced for the support!
