Advanced coroutines - applySort is called twice

In the list with PLANTS, when filter button is pressed emitting of new live data and sorting is executed more than once. I added logging to be more clear:

In List<Plant>.applySort: println("Name: ${plant.name}, position: $positionForItem")

And in val plants: LiveData<List<Plant>> = liveData<List<Plant>> { ... println("Plant list: ${System.identityHashCode(plantList)}")

And this is observed in Logcat:

Same is observed when the filter is press again, but log is much bigger as all plants are shown.

How can this be optimized?
