Part of the Code script is deleted every time I save on the Manual

Part of the Code script is deleted every time I save on the Manual.

The starting code is deleted every time i save on the manual because the starting code is not added on the manual.
Basically, what I did is writing an interface and implemented the interface into a class. Then I am using the class’s methods.

Every time I save on the manual, the Interface and the class at the starting of the code are deleted.

Can you help to post me that code directly here so that we can investigate? :slight_smile:
