Nieprawidłowe usuwanie z List

Piszę w swojej aplikacji ranking i jest prawdopodobnie problem z usuwanie elementów. Nie mam pojęcia co jest źle. Po prostu gdy np. chcę, aby program pofiltrował mi film wg, gatunku wybranego przeze mnie to program wyświetla fakieś filmy, ale to nie są wgl. te, które powinny być wyświetlone. Więc coś wyświetla, ale nie to co powinien.

public void sortRanking(int howSort) {
		deserializationMovie();
		listSortMovies = listMovies;
		
		String dataFromListMovies;
		int position;
		
		if(indexSelectedGenre != 0) {
			
			for(int i = 0; i < listMovies.size(); ++i) {
				dataFromListMovies= listMovies.get(i).getGenre();
				position = dataFromListMovies.indexOf(selectedGenre);
				
				if(position == -1) {
					listSortMovies.remove(i);
				}
			}
		}
		if(indexSelectedCountry != 0) {
			
			for(int i = 0; i < listMovies.size(); ++i) {
				dataFromListMovies= listMovies.get(i).getGenre();
				position = dataFromListMovies.indexOf(selectedCountry);
				
				if(position == -1) {
					listSortMovies.remove(i);
				}
			}
		}
		if(indexSelectedYear != 0) {
			
			for(int i = 0; i < listMovies.size(); ++i) {
				dataFromListMovies= listMovies.get(i).getGenre();
				position = dataFromListMovies.indexOf(selectedYear);
				
				if(position == -1) {
					listSortMovies.remove(i);
				}
			}
		}

			Movie.indexSort = "rate";
			Collections.sort(listSortMovies);
		} else if(howSort == 2) {

			Collections.sort(listSortMovies);
		}  else if(howSort == 3) {

Tak czyszczę JLabel na którym umieszczanie są wszystkie elementy.

sortRanking(howSort);
				labelScroll.removeAll();
				showRanking(labelScroll, ind);
				labelScroll.repaint();
