This code runs just fine for me:
<?xml version="1.0"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx">
<fx:Script><![CDATA[
]]></fx:Script>
<mx:VBox
height="1920" width="1080"
xmlns:s="library://ns.adobe.com/flex/spark"
horizontalScrollPolicy="off" verticalScrollPolicy="off">
<mx:Grid id="floorPlansListDetail" width="1080" height="1920" horizontalScrollPolicy="off" verticalScrollPolicy="off">
<mx:GridRow id="floorPlansDetailRow" width="1080" height="500" backgroundColor="#691a3a">
<mx:GridItem height="500">
<mx:Label id="Name" text="This is a test." fontSize="48" height="200" color="#FFFFFF" visible="true" />
<mx:Label id="Series" text="This is a test." fontSize="20" color="#FFFFFF" />
<mx:Label id="Price" text="This is a test." fontSize="30" color="#FFFFFF" />
<mx:Label id="ElevationA" text="This is a test." fontSize="20" color="#FFFFFF" />

<mx:Label id="Beds" text="This is a test." fontSize="20" color="#FFFFFF" />
<mx:Label id="Baths" text="This is a test." fontSize="20" color="#FFFFFF" />
</mx:GridItem>
</mx:GridRow>
</mx:Grid>
</mx:VBox>
</s:Application>
