2 tab fragments, different url json?

Question

Android

There are 2 tabs with 2 fragments where a json list is loaded in the recycler view. In the code of each fragment there are different json urls. BUT, in each tab in the list, the same list is loaded, more precisely json of the second tab, although in theory there should be one list in the first tab 1, and another in the second. Why is that?
