No tank pressure #2 if no tank pressure #1

[WileCoyote]

I use a Mares Genius.

I dived today with 2 tanks (1 main + 1 deco). My transmitter of my 1st tank was not connected (no battery, works not well ), but the 2nd tank had its transmitter on and connected. Start and end pressure are available in the log on my genius. Pressure graph is also available in genius log.

But on divinglog side, "Profile 3" is empty. And data from tank #2 was empty (had only tank #2 and oxy %, but not volume nor pressure start / end).

Is it normal ?

Thanks
