Search in the mxml file for the DroDownList id="markerStyle" It is in it's own group.
Below that you'll find the ArrayList of those marker objects name="Circle" etc, etc. Try changing those object names in that Array list, and see if that works. Just an idea after quickly looking at the mxml file. Below is a clip of that array. Hope that helps.
<s:HGroup width="100%"
gap="24"
verticalAlign="middle">
<mx:Label text="{markerStyleLabel}"/>
<s:DropDownList id="markerStyle"
labelField="name"
selectedIndex="0">
<s:ArrayList>
<fx:Object name="Circle" style="{SimpleMarkerSymbol.STYLE_CIRCLE}"/>
<fx:Object name="Cross" style="{SimpleMarkerSymbol.STYLE_CROSS}"/>
<fx:Object name="Diamond" style="{SimpleMarkerSymbol.STYLE_DIAMOND}"/>
<fx:Object name="Square" style="{SimpleMarkerSymbol.STYLE_SQUARE}"/>
<fx:Object name="Triangle" style="{SimpleMarkerSymbol.STYLE_TRIANGLE}"/>
<fx:Object name="X" style="{SimpleMarkerSymbol.STYLE_X}"/>
</s:ArrayList>
</s:DropDownList>
</s:HGroup>
