(without directing you to any of the many other comments about this..)
Most likely because you had just joined your Alliance within the last 14 days.
You need to wait until you have been in Ally for 14 days (there is a Timer for you listed on your Ally Event screen, telling you when that will be), before any additional crystals will start giving you points toward the Ally Event.
(if Timer is not there anymore, then maybe you joined about 13 days ago, and your time is now good, but the crystals you already did were done yesterday or this morning while the Timer was indeed still showing some time left)
That's why the ones you already did have only counted towards your Solo Event.
