Is this happening to anyone else? It is rather weird, quest givers are asking for same item twice, but not in a row, in the same quest and more then once.

I've seen this several times. Its not common, but it does happen. There's a limited pool of items quest givers ask for and so sometimes it comes up with the same item twice. I see it most with Maleria, but have also see it with others.

If its happening a lot, something might be up with prices or other parameters involved in item selection and so the item pool may be smaller than usual for some reason.

Thanks for clearing it for me <3 :)
