How exactly are you getting your experience? This sounds like a bug where some mods don't properly update player's experience points and only update player levels which creates inconsistency and to xp upgrade it looks like player doesn't have enough experience in your case for those 50 levels that you want to keep on the player.

any additional info you can provide or should I just close?

That issue with change of number of slots is likely that you opened backpack that was crafted / spawned in before the slot change. The changed numbers only apply to new ones.
