Adjusted view doesn't show values

Hi, i created a view on Activities (specifically on Appointments and Phonecalls) and in case of a Appointment i want to show the locationin the view.

I loaded the standard view in the View Designer (XRM Toolbox), added the field with FetchXML Builder and then i get lost :-)

FetchXML Builder shows the value of the field, the View Designer doesn't... any ideas ?

This is the fetchXML which shows the value as i would like to see it in the view:

<fetch version="1.0" output-format="xml-platform" mapping="logical">

  <entity name="activitypointer" >

    <attribute name="subject" />

    <attribute name="activityid" />

    <attribute name="activitytypecode" />

    <filter type="and" >

      <condition attribute="activitytypecode" operator="in" >

        <value>4201</value>

        <value>4210</value>

      </condition>

    </filter>

    <attribute name="sortdate" />

    <order attribute="sortdate" descending="true" />

    <link-entity alias="a_db1473928199439f864d7945a7a8a9ac" name="contact" to="regardingobjectid" from="contactid" link-type="outer" visible="false" >

      <attribute name="parentcustomerid" />

      <attribute name="fullname" />

      <attribute name="abw_internalmanager" />

    </link-entity>

    <link-entity name="appointment" from="activityid" to="activityid" >

      <attribute name="anth_location" alias="Location" />

    </link-entity>

  </entity>

</fetch>
