Hall effect sensor polerity swap?

So i have a Ez30 boxer engine whit 2 hall effect sensors, and for some reason do the sensor changes direction or what is happening?

i still get the trigger, it just turns around from falling to rising mid rev.

the ecu dosent say anything exept that the valid travle is way off.

full sync level

how do i solv it?, is it the sensor thats wrong? cabels? i found a forum post that did say this is how the sensors works, that thy switch polerty some tims?

btw, dont mind if the triggers dont match what its suppose to be, i dont know the resolution of the log, just that i found that thy are swapping polarity
