I have looked around the 8th and 9th floor it says 8th floor in the dungeon and in the Journal  but, on the guild job board it says the 9th floor.I have found two suspicious looking Boulders on the 8th floor but, when I approach them they don't do anything. 

also one more glitch, I found if you run out of monster lure while in a bottle spot it will display the floor map, the bottom icons, and, text that says you have run out of monster lure.

Hello, the objectives is the correct one. The quest happens on the 8th floor. I'll fix the wrong entry on R35, thanks for reporting the issue.
