Application Icon Not Visible From Dock Display-How to Fix?

[Silverstring]

For some reason, some icons (Twitter for Mac) among them, are not showing up when I click the application folder in the dock. COMPLETELY not showing, as if they don't exist, not even with the white place holder and "anti-" sign (circle with a diagonal line through it) placeholder as sometimes happens with OS X. Doesn't matter if I show list, or grid, or automatic, there is no icon for Twitter for Mac at all, nothing between Tweetdeck and Typinator.

However, when I go to the finder and click on the Applications folder, it is there. In between Tweetdeck and Typinator as it should be. The applications can be launched as well, so they were installed properly.

Any reason for the disconnect? Why it would show up in one place but not the other? I always thought the dock folder was supposed to be an exact mirror.

Does anyone know how to fix?

Drag the Applications folder off the Dock and let go.... poof!
Now drag the Applications folder from Finder to the Dock to re-create it.

​

To make it look like a folder again, right-click on it and select Display As > Folder

If that didn't work, it could be that you have more than one Applications folder. But, you haven't given enough information (location) for anyone to help out, if that's the case.
