The rule is that 'id's must be unique. JavaScript will only find the first one. I don't know why you're getting nothing except that each 'id' should be different.

Because I need to show the values on different areas. What is my options to make it happen?

Your code is looping over the localStorage domain and finding key values which it is linking to elements in the document.
You only have one key : value pairing for each key value - so this should map to a single element. I don't understand why you have two lables with the same ID - do you want to set both to the same value?
If that is the case then rather use a class or a data-attribute and then use that in your selector for setting the values.
But I would be interested to know if you really want to target more than one element for a single key:value (localStorate) pair or if it should be a single LS value to a single document element?
