I opened few different souls today, 1-3*, rare souls, wanderer soul in a few hour intervals, result?

3x 3* sentinel chopper, is this normal or it's a bug? I also got duplicated speed of light eddies few days ago, so who generates souls and allows duplicates or more in such a short time? It starts to remind me on wending machine where you get the same result over and over again and stops being exciting to play.
