why when i want my athena (lvl 50) to inherit from my amora (lvl 50), she is like having many exp but not all of amora's exp from lvl 1 to level 50?
note: athena has 2107600 more exp to level up and i think the total exp of amora from lvl 1 to 50 is more than 2107600. athena's exp bar is still the same when i try using a lvl 40 angel.

As far as i know from level 1 to level 50 is not much experience.
