I just tried 2.1.9(3) and cannot reproduce the issue you reported: it correctly registered all the button clicks I did.
Since you said it’s inaccurate: how off is it?
Also, I assume you are using the stock firmware 2.1.9(3). If you compiled the firmware yourself, I can think of many reasons why it may not be accurate.
