Capacitive touch hat not working always

Hi,

I purchased one of these (https://shop.pimoroni.com/products/adafruit-capacitive-touch-hat-for-raspberry-pi-mini-kit-mpr121) and connected it to my Raspberry Pi 3 Model B. The hat fits physically and that's great. However, my RasPi does not always detect it always. If I push it down here and pull it up there it works but most doesn't. My project needs compactness (hence I bought the hat) and I don't want to solder the hat onto the Pi permanently.

What's the solution? I actually intend to buy another one if this can work always. I have another RasPi of the same model.

Thanks
