How to remove shared connection URLs from SmartView options history

SmartView version: 21.110

I have tried removing URLs from Properties.xml from the following locations but I don't see any of the URLs listed on options. I see only below content on the xml file.

<cfg>

  <provider>

        <url>http://server:port/workspace/SmartViewProviders</url>

  </provider>

  <helpurlcontext></helpurlcontext>

    <extensionupdatelist>http://server:port/extensionupdatelist/UpdateList.xml|%SVCLIENTINSTALLPATH%/extensions/UpdateList.xml</extensionupdatelist>

  <!-- Add support for uploading to NR library - use SV private connection url

<libraryprovider>http://server:port/epm/SmartView</libraryprovider>

   -->

  <!-- Add authentification proxy cookie name(s) here.

  <authCookie name="SSO1"/>

  <authCookie name="SSO2" valueLoggedOut="LOGGEDOFF"/>

   -->

  <!-- Add authentication web page marker here.
