Mobs are low! Less monsters are appearing!

So yesterday I just configured the database for Castle Siege (for the castle to be owned by my guild), but then after I configured it, the spawns became less! There were less monsters, from 5000 monsters to 2770 approx. monsters according to the Game Server. What should I do? Thanks in advance!

Can you exactly describe what you configured on your database?
and also revert it back? because by configuring the database for castle siege it does not affect monsters normally.
