Imac Mouse Right Click not working

I have a problem when trying to use a right click on my Magic Mouse. The right click function just doesn’t work even if it is enabled in System Preferences (Mouse --> Preferences --> Secondary Click enabled to “Right”). When I change the secondary click to “Left,” the “Right click” function works perfectly fine (using the left click as an activation button). However, when they change it back to “Right,” the “Right click” function stops working again.

How can I fix this problem?
