Bridge Dropdown No Longer Shows Up on PaperUI

Hi,

Can someone verify that “Bridge” dropdown is still shown on the latest Openhab2 nightly build (openHAB 2.2.0 Build #1058)? This issue applies on both IDE and Snapshot. In my custom binding, I have thing defined as below in ESH-INF .xml:

<thing-type id="topic">
		<supported-bridge-type-refs>
			<bridge-type-ref id="broker" />
		</supported-bridge-type-refs>
		<label>XXXXX</label>
		<description>YYYY </description>
 		
		<channel-groups>
                   <channel-group id="abc" typeId="abc" />
                   <channel-group id="xyz" typeId="xyz" />
               </channel-groups>
	<config-description>
              <Param> ......
	</config-description>
	</thing-type>
	
</thing:thing-descriptions>

UPDATE: I reliazed that this only happened on discovered things and not manually added things. Wondering what has changed since previous builds on Discovery
