Question Experience points

The experience points are going up but when it levels up it stays at the same level and the bar that marks progress just starts from zero again.  Is anyone having the same issue.  It's happened like 3 times on a row for me.  

Once you get past the starting level of 'Chickling' and move to 'Starter' (at 50 XP) it changes so that when the low bar reaches maximum, the upper bar will increment. When the upper bar reaches maximum you will get 1 XP

The upper bar has not moved and the bottom bar has filled up 4 times now.  What do you recommend I should do?

I just noticed that today. In the past two weeks my XP number didn't budge. Then today my region was moved into a different grid, and the bar started progressing. Once it topped off I saw that I gained the point here on the website, but the XP number on the hud was the same. I detached the hud, reattached, clicked and selected Account, My XP. At that point the hud updated.
Hope that works for you.
