Eversong Woods - Deactivating the Spire - Duskwither Spire Power Source not showing correct effects

Quest - http://wotlk.openwow.com/quest=8889

The three Duskwither Spire Power Sources (http://wotlk.openwow.com/object=180920 / http://wotlk.openwow.com/object=180919 / http://wotlk.openwow.com/object=180916) don't have any green effects flying towards the little crystals beside them. The little crystals could be the Duskwither Spire Power Source Satellite http://wotlk.openwow.com/object=182092 but im not sure if thats right.

The Duskwither Spire Power Sources should also stop throwing the green effects as soon as you activate them with the Deactivating Jewel http://wotlk.openwow.com/item=24337.

Here's a video of how its supposed to look - https://youtu.be/9Grj3md1_fI?t=40s
