Airfit P10 Passive Venting

Airfit P10 Passive Venting

I have been trying to find out that info about passive venting showing up as steady mask leak for a while.
If anyone has any information that would be great. 
I switched to a brand new P10 and can feel the air blowing out of the exhaust vents my old mask was plugged and not venting.
Leak rate showed up in old mask at zero leak consistently in Oscar the new mask shows a steady leak rate in of 10 L/Min.
I switch back to older mask body leak goes back to zero but vents seem plugged on old masks and haven't had much luck getting them cleaned out. I have seen the ideas on cleaning mask old mask with Dawn dish soap and water pick and will try.
I tried a second new mask and it to showed a consistent leak in the same range of 10 L/Min and mask is sealed to my nose great no leak there.
The only other difference in the old mask to the new ones is the tubing is quite a bit shorter on the new masks but I doubt that would do anything.

The ResMed mask documentation contains the vent flow rate for all their devices. 

FWIW, I chased ghost leaks for a few months. I have two identical machines with the same hoses and masks. While in use, one has a steady 4 l/min leak and the other has 0 l/min leak. If I switched the hose and mask between machines the leak followed one of them and the other still showed no leaks. 

In the end as it was well within the spec of the machine and had no impact on therapy, I just put it up to my OCD tendencies and put it on the mental shelf for later analysis. Then promptly forgot about it until now.

What does the OSCAR chart look like regarding the leaks?

Hi Thanks
This is the chart with the consistent leak
The old mask with blocked vents is zero leak.
