XP bar

[chiefmack9]

Not sure if this is the right place, but for some time now, have been seeing a quite perplexing issue with my Xp bar. I dont Ding next adventure lvl, till i have hit 100.9. Also XP numbers go up and down off and on. At one time will read 55.6, then 55.8, then 54.9 55.3 then 56.0.? Any information would be helpful. It is just annoying, but I can live with it, as i have.

Thanks
