Secret Training room, wont advance, cant get back in

[Moro-sama]

For the Destroyer lvl 10 secret training room where you are supposed to get the gloom bug thingy, didnt matter how many times i did it right, it wouldnt advance.  Tried doing the escape to see if i could get out and maybe start over, now i'm just stuck outside with the quest flashing its help stuff at me ~ can't abandon, cant get back in, can't advance  T~T
