Synchronizing Selective Settings as read-only for a team

I have some Scala formatting settings for IntelliJIDEA 15 Ultimate Edition that I want to share with my team.

The method we used with no success:

• go to Preferences > Tools > Settings Repository
• Uncheck "Auto Sync"
• Add the read-only source our settings repo: git@xxx:yyy/intellij-settings.git

The repository contains scala.xml in the root folder with this content:

<application>
  <component name="ScalaSettings">
    <option name="SHOW_TYPE_TOOLTIP_ON_MOUSE_HOVER" value="true" />
    <option name="COMPILE_SERVER_ID" value="c0fffcbc-9ce0-4824-9d96-77e4dd39e9e4" />
    <option name="COMPILE_SERVER_SDK" value="1.8" />
    <option name="COMPILE_SERVER_SHUTDOWN_IDLE" value="false" />
  </component>
</application>
<code_scheme name="XXX Scala Standard">

And ./codestyles/CompanyStandard.xml with the following content: 

  <ScalaCodeStyleSettings>
    <option name="WRAP_BEFORE_WITH_KEYWORD" value="true" />
    <option name="ALIGN_IN_COLUMNS_CASE_BRANCH" value="true" />
    <option name="ALIGN_COMPOSITE_PATTERN" value="false" />
    <option name="SPACE_AFTER_TYPE_COLON" value="false" />
  </ScalaCodeStyleSettings>
  <XML>
    <option name="XML_LEGACY_SETTINGS_IMPORTED" value="true" />
  </XML>
  <codeStyleSettings language="Scala">
    <option name="ALIGN_MULTILINE_EXTENDS_LIST" value="true" />
    <option name="CALL_PARAMETERS_WRAP" value="5" />
    <option name="METHOD_PARAMETERS_WRAP" value="5" />
    <option name="EXTENDS_LIST_WRAP" value="1" />
    <option name="FOR_STATEMENT_WRAP" value="2" />
    <option name="IF_BRACE_FORCE" value="3" />
    <option name="FOR_BRACE_FORCE" value="1" />
  </codeStyleSettings>
</code_scheme>


Am I doing something wrong?
