Kotlin FragmentStatePageAdapter destroy view on third swipe if it has more than 2 items - kotlin

Question

I have set the FragmentStatePageAdapter to swipe through fragments of the same layout and different data (users profiles).
When I give it list of 2 items all work well.
If I give it 3 or more items it creates views for fragments, but on third swipe contents turn blank, regardless to which direction I swipe (forward then forward, forward then backward). If I accurately slide to third item when still holding the screen I can see it's valid contents, but when I finish slide releasing the screen all disappears.
Page Adapter is set like below. (swipeList is list of users' ids, swipeEntityType == 0, each User contents is loaded by "uid" passed through bundle)
class SwipePagerFragment : Fragment() {
private lateinit var parent: MainActivity
private lateinit var state: State
private lateinit var ctx: Context
private lateinit var swipeList: MutableList<Int>
private lateinit var pager: ViewPager
override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?,
savedInstanceState: Bundle?): View? {
val view = inflater.inflate(R.layout.fragment_swipe_pager, container, false)
parent = activity as MainActivity
state = parent.state
ctx = state.ctx
swipeList = state.swipeList
pager = view.findViewById(R.id.fragmentSwipePager_pager)
val pagerAdapter = ScreenSlidePagerAdapter(childFragmentManager)
pager.adapter = pagerAdapter
return view
}
private inner class ScreenSlidePagerAdapter(fm: FragmentManager) : FragmentStatePagerAdapter(fm) {
override fun getCount(): Int = swipeList.size
override fun getItem(position: Int): Fragment = when (state.swipeEntityType) {
0 -> {
makeUserFragment(swipeList[position])
}
else -> {
makeEventFragment(swipeList[position])
}
}
}
private fun makeUserFragment(uid: Int): UserFragment {
val bundle = Bundle()
bundle.putInt("uid", uid)
val frag = UserFragment()
frag.arguments = bundle
return frag
}
private fun makeEventFragment(eid: Int): EventFragment {
val bundle = Bundle()
bundle.putInt("eid", eid)
val frag = EventFragment()
frag.arguments = bundle
return frag
}
}

Setting
pager.offscreenPageLimit = swipeList.size
solves my problem
