I lost a ranked because of this client

So basically i was trying out one of those apps where you earn coins for missions and then use them for rp. One of them was a win with 10 assists so i thought it would be easiest for support. I switched the ranked lobby to normal draft. I lost the game which was fine but then I heard the lp demote sound and realised that i was actually playing a ranked game. When i went back to the lobby it tried to switch again but this time i noticed that when i clicked the normal draft button, it wouldnt change at all, the game mode wouldnt change for any gamemode, meaning it was bug. Please riot we've had this client for years and there are still so many bugs, i hope one day riot can improve the client instead of changing it and leaving it to burn.
