Facebook Notifications?

[john]

Hi,i have a question,i've been a member of facebook and 9gag for some time now,and for a longer period the notifications on my facebook page,from 9gag aren't working properly. I have selected that i want to get notifications from 9gag,and I get notifications for friend request,tags,likes,comments and everything else,even from some other pages and stuff. I've tried on my pc and on my mobile. Now here's what's the problem,after i comment on something on 9gag,i like to..lets say track the progress,but i've been unable,since after my activity on 9gag,after some time,when someone respond or likes it,i get a notification on facebook,but only for a second,when i open it in a new tab or window,it stays there marked red 1 on a notification,but when the page fully loads it disappears,also when I try to open it while it's still there,nothing happens,like i never got it. Also,sometimes i get notifications from 9gag,from people's replies,but that's like 10% of my activity. Thanks for any help and sorry for the long message. Will give best answer if someone helps
