One is clear changing, the other is assert changing. There should be info in syslog or whereever you redirect ntpd's logging to. Let's take the detailed discussion off list.

A common error is to have pps flipped. The leading edge should fall on the second.

Fix it with a NOT gate or in a configure file No need to add inverter latency. ppstest says the 'assert is the right edge. Just use that edge. gpsd autodetects the proper PPS edge. Excapt on RasPi where you use a kernel config to use the other edge. ntpd by default uses the assert edge, which is the case here. It can be told in the ntp.conf file to use the clear edge instead.
