Custom XP Drop Messed Up XP bar

was trying to make a custom boss entity drop a xp orb, with the command

/summon XPOrb ~ ~1 ~ {Value:10000s}

, it summons an orb but serveral things happen, first Player picks up Orb, the exp value is not added to the bar, then any other orbs the player tries to pick up after that will have no effect either
