Slider buttons and o-rings are a wear item (probably need replacing every 1,000 miles or less), so probably no warranty. Did you replace the o-rings w/ the OEM ones? I had my clutch apart this weekend and noticed that the OEM ones are made of a pretty hard material, most likely to withstand the heat. I'm guessing that hardware store replacements would fail pretty quickly. If you put in new OEM buttons and o-rings then maybe you'll have valid warranty claim, but I'm guessing if they failed in two days of riding, then you did something wrong on the install. Could also be that there is something else wrong with your clutch (spring cup bushing comes to mind), which is causing your issue.
