Hello

I need help or insight into what went wrong or generally what is wrong with this board.

Okay, I recently removed Kailh blue switches and soldered Gateron KS 3 Red switches into my old keyboard. at the beginning, I plug my keyboard to my pc and everything looks normal for the first 5 minutes until the capslock row down to numpad 6 pressing continuously. I decided to remove the switches from the Capslock row and it still pressing! I need help or solution to this problem.

Thanks!

Btw, this is my first soldering new switches into keyboard.
