Maestro: InvokeURL Fusion widget incorrectly saving AdditionalParameter values

[geomapper]

When trying to configure an InvokeURL widget in fusion with multiple AdditionalParameter objects, upon clicking "Save" the widget automatically overwrites the AdditionalParameter values with copies of the first AdditionalParameter.

For example, when I configure the following InvokeURL widget in Maestro:

<?xml version="1.0"?>
<WidgetType xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema" xsi:type="UiWidgetType">
  <Name>Report Generator</Name>
  <Type>InvokeURL</Type>
  <Location />
  <Extension>
    <Url>http://localhost/Scripts/FormGenerator.php</Url>
    <DisableIfSelectionEmpty>true</DisableIfSelectionEmpty>
    <Target />
    <LayerSet>
          <Layer>Testlayer</Layer>
        </LayerSet>
    <AdditionalParameter>
          <Key>Selected</Key>
          <Value>$CurrentSelection</Value>
        </AdditionalParameter>
    <AdditionalParameter>
          <Key>DesiredField</Key>
          <Value>MASTERID</Value>
        </AdditionalParameter>
    <AdditionalParameter>
          <Key>LayerName</Key>
          <Value>TestLayer_Name</Value>
        </AdditionalParameter>
    <AdditionalParameter>
          <Key>URL</Key>
          <Value>http://localhost/TestFiles/reporttable.asp</Value>
        </AdditionalParameter>
    <AdditionalParameter>
          <Key>DestinationKeyName</Key>
          <Value>MASTERID</Value>
        </AdditionalParameter>
  </Extension>
  <ImageUrl>images/icons.png</ImageUrl>
  <ImageClass>options</ImageClass>
  <Label>Report TEST</Label>
  <Tooltip>Report TEST</Tooltip>
  <StatusText>Report TEST</StatusText>
  <Disabled>false</Disabled>
</WidgetType>

Whenever I click "Save" the widget automatically changes itself to look like this:

<?xml version="1.0"?>
<WidgetType xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema" xsi:type="UiWidgetType">

  <Location />
  <Extension>
    <Url>http://localhost/Scripts/FormGenerator.php</Url>
    <DisableIfSelectionEmpty>true</DisableIfSelectionEmpty>
    <Target />
    <LayerSet>
      <Layer>Testlayer</Layer>
    </LayerSet>
    <AdditionalParameter>
      <Key>Selected</Key>
      <Value>$CurrentSelection</Value>
    </AdditionalParameter>
    <AdditionalParameter>
      <Key>Selected</Key>
      <Value>$CurrentSelection</Value>
    </AdditionalParameter>
    <AdditionalParameter>
      <Key>Selected</Key>
      <Value>$CurrentSelection</Value>
    </AdditionalParameter>
    <AdditionalParameter>
      <Key>Selected</Key>
      <Value>$CurrentSelection</Value>
    </AdditionalParameter>
    <AdditionalParameter>
      <Key>Selected</Key>
      <Value>$CurrentSelection</Value>
    </AdditionalParameter>
  </Extension>
  <ImageUrl>images/icons.png</ImageUrl>
  <ImageClass>options</ImageClass>
  <Label>Report TEST</Label>
  <Tooltip>Report TEST</Tooltip>
  <StatusText />
  <Disabled>false</Disabled>
</WidgetType>
