> is this behaviour normal 

It is not normal behavior to store 2 entries when you only want 1.

Likely your code has a bug in it which causes this behavior. Debug your code to find the issue and fix it.

    Hi,

    Generally if something does not work as you want, yes you have to do some changes. If you can delegate the work to somebody else, this is also an option.

    Here are tips how to ask a good question on a technical forum such as this one:
