Items being repeated in a RecyclerView

I have a fragment v4 that is managed by a SectionsPagerAdapter . In fragment I have a RecyclerView that has a Adapter custom that receives a ArrayList that contains exactly 96 objects, which represents the hours of the day, ex: position 0 = 00:00, 1 = 00:15, 2 = 00:30, 3 = 00:45, 4 = 01:00, and so on until 96 = 23:45. In addition to the time itself, it also has a nome field and a procedimentos field. These fields will only be filled if someone is scheduled for the time, otherwise they are "" .

The problem is that it is shuffling everything when it comes to assembling the adapter! One time it repeats in several random places that have not yet been scheduled ... by what I noticed in log , as does scroll in recyclerView , it automatically updates adapter ... I think that's what this bug ... but I do not know how to solve ...

Note that in the image below, it should have appeared only at position 01:45, but it also appears at 00:30, detail that at this position of ArrayList the name field is empty.
