Huntsman mini too sensitive(in a bad way) and lightnning issue

I have problems with my keyboard, every time I press a key it registers too many times and very quickly, so that when I try to write this text, even if I press the key normally, the key registers more than 1 time (when that It didn't happen before) and I also have an error because it happens to me that the number 8 on my keyboard has red lighting (although I don't have it configured that way, I don't know if it is telling me that something is wrong with the keyboard or it is simply a lighting error, if you could help me correct this, I would appreciate it.
