Sorry to step in, but I had a slight expansion or riff on Cheese's explanation. On every normal monster battle, the EXP value appears to change once the results tab shows up: if you face two monsters, kill one, then spare or flee from the other, your EXP value does not change until you've completed the battle.

Since that tab doesn't show up for the bosses, the game may be referring to some other part of its code to gather information for altering EXP, like a scripted event, and not to the normal EXP value from standard monsters. It could be the case that EXP changes are tied to particular values, and so cannot be varied as it is for auto-leveling, it could be that there is an actual flag triggered for recalculating EXP when the results tab comes up, and so there needs to be a workaround without that tab, or it could be some other reason.

If that's the case, then it would make sense that the bosses have either no EXP data, or that data is set to 0.

This is purely speculation on my part about how the game is coded. I don't have the necessary information to double-check the code itself and confirm the website's numbers.
