Adamson and Stjernberg Drugstore area in Batman: Arkham City

[Alln.Do]

Anyone here have any idea on Adamson and Stjernberg Drugstore area? I am actually for a few reason in my game unable to destroy the wall in front of the pharmacy, I stood in front of her and been attempting to place the explosive gel on the wall, but i just put it on the floor over the frame or either side of the wall area. It's as if the party believes that the wall is there for the purposes of moving through it, but then I do not think that is there in order to place the explosive gel.

Here i too have the similar trouble. I gave up and continued with the story (as you may have at present). I'm just posting this looking for any other person can only move forward. Once you try to move on, they have the task of analyzing all the robots. Once you analyze all the robots, the video shows a ninja open a secret panel in the pharmacy, eliminating the annoying wall. Back to the pharmacy, the attempt to access the panel, counter the attack, and voila, no wall.
