Problems with data

Hello. I have 2 Resmed S9 Autosets (home & travel). As far as I can tell, they're set the same but I'm getting funky readings from my travel machine. Here is a good nights graphs in Sleepyhead.

Next night I'm traveling and use the other machine. Here is that day's data in Sleepyhead.


As you can see the scale is off the wall with the travel machine. It's showing a flow rate of over 2,000 lpm.

Any ideas or suggestions would be appreciated!
