Possible model view coordination problem

I'm not sure if my problem due to my model or the Orbeon xform engine. Has anyone else seen this problem?

The below xforms fragment causes problems in both the view and the model. When a new instance of addFilesystem is created the inner (contacts) <xforms:repeat/> gets an additional row in both instances of the addFilesystem element. For example, if a single instance is initially defined with three rows of contacts in the main model when the second instance is created both instances in the view are updated with four rows. However, when the data is saved to an XML file the second instance which has been dynamically created only has one row while the initial instance has only its initial 3 rows.

<xforms:repeat nodeset="xxforms:instance('addServers-instance')/addFilesystem" id="addFilesystem-repeat">

  <fr:datatable>

    <xforms:repeat nodeset="xxforms:instance('addServers-instance')/addDatabase/contacts-list/contacts">

      ...

   </xforms:repeat>

  <fr:datatable>

</xforms:repeat>
