Garmin MK3i causing Error message of Warning: smaller number of gases (1) than cylinders (2).

[John Dayton]

Using latest Version of Subsurface 6.0.5504 on a Win11 computer. I'm trying to import my .Fit files into the program from my Garmin MK3i with 2 transmitters (mine & my wife's). When I start the import I get a red bar at the bottom of the main Subsurface program screen with this error:

Warning: smaller number of gases (1) than cylinders (2).

This process worked fine with my MK1, I'm thinking it may be because of the two transmitters. 

Anyone else encounter this or have any thoughts? Thank-you! John

This warning is expected, as what you are doing (monitoring the tank pressure of something that is not one of the dive tanks configured in your dive computer) is an edge case, which is triggering a warning in Subsurface.

I was seeing one thing and thinking it was my problem, But I just sorted it out. Thanks for your input!
