From your FIT file it seems that you have more than one tank pod connected to your Garmin, but only one gas mix defined. That confuses our code a bit and it thinks that the second pod is connected to a dive with undefined gas data - and then it defaults to air for that.

Do you actually have more than one pod attached? Are you using both? How does this look in the on-watch settings?

I'm trying to figure out how to parse this correctly, but since I only have one pod, this isn't something I can experiment with here...
