Install Appbrain free app and sync all your apps with it. Certain app that not shown on market will be shown on Appbrain where you can update.
Thanks bro for your sugesstion.

Did you install any apps from Samsung Apps? If yes, they won't be shown in your Market installed apps..i think

All apps that showed as not installed are apps dowloaded from the market.
I guess i have no choice but leave it that way coz I still can launch the apps even if it is showed under not installed.
Thanks for all the replies.
