Dpad stops responding after multiple inputs

Whenever I move from side to side quickly on my dpad and then hold on the last input, it stops responding until i release the button and press it again. This doesnt happen with the joystick. Im not sure if this is a software issue but I did take mine apart to have a look and didnt see anything obviously wrong or misaligned internally. I dont think its a streaming or lag issue because I can replicate it with the brightness slider from the portals system settings. Is there a hardware issue that I should be looking for that may cause this? I did notice that the blue ribbon under the silicone cap was a little lose and not touching the board on one side but not sure if that would cause this or what to use to secure it to the board.
