Demon Wall Problem

So this is my problem. I don't see the ground marks: http://cubeupload.com/im/x985QO.png , screenshot (is from youtube). I just don't see it. I keep wiping my teams because I can't react to the boss. We managed to push through somehow yesterday and got to the last boss of AK.

I didn't see his apparently purple glow when you have the bomb and need to run away. Which meant, I wiped the team because I dropped the bombs were I stood.

I never changed anything in my settings, never had this problem with anything before.. I'm hoping someone can help me because I'm really getting frustrated here.
