Rating mistake

I apologize to Steam and CERO. It is my fault to fill the wrong age rating system and then made troubles to them. Now the game was removed and now is back again. Also apologize to players. About the age rating system, it should ask the age rating organizations to determine. I misunderstood the system and then chose a rating by myself. Because this is my first time to meet this so I did not do the right thing. I should ask others for more information.
I apologize again to Steam and CERO and thanks to the tolerance.
