[Help] Raid Boss Status

[Syntax]

I need a little help at something. I used normal raid bosses on my server. I modified the level to 85 and also modified respawn time, but i have a problem. I use an online status checker.

 

The problem is: When a raid boss spawns it should modify the column respawn_time from raidboss_respawn table to 0. But it doesnt. It only modify his status to 0 if i rr the server.

For example last night, Ember Raidboss spawned. But when i checked the table Respawn_raidboss at column respawn_time for Ember his value was bigger than 0. How can i do it so when a raidboss spawns to update respawn_time to 0??? Any suggestions?
