Somehow missing "pressure" data for a session?

Somehow missing "pressure" data for a session?
Hi

So I just imported my data from last night, and I noticed that for some reason, there's no pressure data showing for the second session of the night.

   

As far as I know, I haven't done anything differently. I tried purging the day's data and reimporting it from the SD card a second time, but it still doesn't show the pressure data for the second session. It's not a HUGE issue (I'm on fixed pressure right now) but I'm wondering if anyone has any ideas?

Thanks in advance.

So I just took a short nap and the pressure data was visible for this new session. The previous session's pressure data is still not showing, though. As far as I can tell everything is okay aside from that one session.

I have seen this only once before, so it as been hard to isolate. I'd very much appreciate getting a zipped copy of your SD card. If you are using version 1.2.0 you can use the Help menu, Troubleshooting, Create zip file of CPAP data card - then upload it to our receiving Dropbox https://www.dropbox.com/request/6VeFzBXa4qZ37EgphL5b
Please put your username in the file name so we can track it

OK, I just left that file uploading. I manually backed up the SDCard prior to my nap, too, so if you need any files from prior to the nap for comparison, I can send them to you separately.

Let me know if there's anything else I can do.

Finally got this sorted out. It seems that sometimes the machine doesn't write real data into a data record, and if the pressure has been constant all session, we have a starting pressure but no ending pressure point. So, one point, no line. The solution is to add the final point using the most recent value with the new time.

The fix will show up in the next release, and you will have to purge and rebuild your data - if you remember, and still care Big Grin

Ahhh amazing! Thank you for letting me know. I may do... it's the sort of thing that will bug me. LOL but if not, at least I know it won't be an issue going forwards. 
Thanks
