Blue essence disappear

When i opened up my first 2 BE bubbles from the mission i got them both but the next day it just disappeared from my BE indicator or whatever they call it. Then i played a few matches and leveled up to 31 and got 2 champion capsules ,shredded them for blue essence and got back the 5000 BE that i opened from the bubbles a day ago and got the BE that i got from shredding the champion capsules. The next day ,again its gone. Any help? Did this happen to anyone else?
