There is an issue on PS4 (or a feature, I don't know...) that the PDA's that are already picked up respawn after some time. So you can pick them up again, but as you have already downloaded their content, nothing happens. This could be the behaviour you're seeing ? It's annoying, but not game breaking.
Another issue that is annoying is that the precursor force field doors reset after some time (or after reloading), so that you have to craft additional tablets to go back to the places you have already visited.
I do not know if both issues are known by the developers and being worked on.
