Hello, I did the keldeo quest till beating the forestmaster npc , also did the other two wishiwashi part and the arcanine part. However after doing the forest master which I did in the last, I use escape rope to matsuki town but the guards won't let me enter the shrine. Also this NPC shows the dialog as shown in the picture below which it shouldn't unless the quest is complete. 
I went to the forest maze to check if I did the quest properly, just in case. But the levers which let me enter the boss room don't show response which means my quest part is done here. 
As you can see the quest isn't trigegring anymore that means I did the quest. I do not know how to continue the quest any further so please help me out by fixing the bug.

If you want to go back to the Forest Boss after leaving once you have to interact with the treestump with mushrooms on it instead.

Also make sure to double-check if you talked to the Golem after the Charizard boss in the mountain maze area and double check if you interacted with the rock, back in the room at the underwater area.

Oh , hey thanks , I have missed the rock on the wishiwashi area. Thanks alot!
