 I have some similar problem when trying to add the custom 128bit characteristic UUID.
The service UUID is advertised correctly but the characteristic UUID not. 
 I add the Service like this 
 #define MIDI_SERVICE_UUID {0x00,0xC7,0xC4,0x4E,0xE3</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Wed, 02 Mar 2016 08:57:56 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/12247/custom-128-bit-uuid-characteristic-not-based-on-the-service-uuid" /><item><title>RE: custom 128 bit uuid characteristic not based on the service uuid</title><link>https://devzone.nordicsemi.com/thread/46332?ContentTypeID=1</link><pubDate>Wed, 02 Mar 2016 08:57:56 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:1bd15158-8e6c-4c9c-a0d3-eb5b3a4b9998</guid><dc:creator>Petter Myhre</dc:creator><description>&lt;p&gt;Thank you for answering and helping community.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: custom 128 bit uuid characteristic not based on the service uuid</title><link>https://devzone.nordicsemi.com/thread/46331?ContentTypeID=1</link><pubDate>Tue, 01 Mar 2016 15:57:51 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:02697572-aed1-4aee-ac31-196cb402f014</guid><dc:creator>Cincheza Ovidiu</dc:creator><description>&lt;p&gt;Eventually I found the problem. Before adding the characteristic the base uuid needs to be updated with the base uuid of the characteristic by calling sd_ble_uuid_vs_add(&amp;amp;base_uuid, &amp;amp;p_lbs-&amp;gt;uuid_type);&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
