Notepad++ has a setting that controls the auto-completion behavior.
Settings -> Preferences -> Auto-Completion ->Auto-Insert
Edit:
Your requirement:
We need to type quotes twice for them to appear and when they do appear, there are two of them.
This behavior is controlled by Keyboard language settings in Control Panel. Go to
Control Panel -> Regional and Language -> Keyboards and Languages
and select a keyboard language which requires typing twice before quotes appear.
