Swift Fx high rate of air escape at elbow

[808imiloa]

Recently switched to ResMed’s Swift Fx pillows. More secure fit than the P-10. My problem is there is a high rate of air coming from the vent which Myair report is always a 13 with a adjust mask notice. I know there is no leaking from around the pillows or the pillows itself nor the swivel. Any workarounds or solutions? Thanks
