Magic Trackpad Click Not Recognised

I've got a problem with BTT and my Apple Magic Trackpad. Every so often, it doesn’t seem to recognise a click. I have to click several times for it to be recognised. At other times it works fine. I've switched BTT off and the problem goes away. I've studied the settings of BTT to see if I can work out what might be causing this but I can't find anything. Has anyone encountered this problem before? Could you suggest a way to fix it as I'd like to switch BTT back on. I find the shortcuts very useful.

Best wishes and many thanks
