If the Dock on your Mac contains an icon with a question mark
If an app’s icon is in the Dock and you delete the app from your Mac, the icon remains in the Dock but is covered by a question mark.
Remove the question mark icon: Drag the icon out of the Dock until you see Remove.
To download again an app you purchased from the Mac App Store, see Install and reinstall apps.
