Item Set Improvements

I want to just start off with saying that Item Sets are great right now and i'm not gonna be ranting super hard about how it needs an improvement, as I understand that Item Sets aren't really Riot Games main priority, however there are a 2 major bugs right now that have been bothering me in the Item Sets for a while.

1. Item Set will randomly add a Control Ward at the bottom of your Item Set in game, not in the Item Set editor, resulting in no way to get rid of that Item from the Item Set (Really Really Frustrating)

2. Stinger as of now is just a blank icon, and can't even be found if you search for it, or narrow it down using the filters.

Now I just want to talk about the other game mode items in the Item Sets, which I think should be filtered out. No one really uses the game mode Items in Item Sets, so if we could make a separate filter in the Item Set editor, that would really help with finding items faster, as well as make everything on the screen less crowded and more organized.
