Custom Report Not Prefiltering

I have created a custom report using BIDS and have uploaded it to CRM Online.

The report is not prefiltering (i.e. it is only sitting in the option 'Run on all reports'). I have also uploaded the report to a test organisation and it works fine. I can't see where the error is! My query:

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

 <entity name="quote" enableprefiltering="1">

   <attribute name="name" />

   <attribute name="customerid" />

   <attribute name="statecode" />

   <attribute name="totalamount" />

   <attribute name="quoteid" />

   <attribute name="createdon" />

   <order attribute="name" descending="false" />

   <link-entity name="account" from="accountid" to="customerid" visible="false" link-type="outer" alias="acc">

     <attribute name="name" />

     <attribute name="address1_postalcode" />

     <attribute name="address1_line2" />

     <attribute name="address1_line1" />

     <attribute name="address1_stateorprovince" />

     <attribute name="address1_county" />

     <attribute name="address1_country" />

     <attribute name="address1_city" />

   </link-entity>

 </entity>

</fetch>
