Oscar 1.4.0 = DS2 Flow Rate waveform missing in Graphs display

Oscar 1.4.0 = DS2 Flow Rate waveform missing in Graphs display
My Oscar 1.4.0 importing data from Philips DS2 has been working well all along displaying 12 graphs (Daily view) including Flow Rate graph. However, beginning September 18 till 20,2022 (for no reason) only 6 graphs were shown and the Flow Rate graph was not there. There are still 12 events in the Event Types (lower left) including FL. On September 20, I went into the menu File\Preference\Waveforms and checked Flow Rate and few other graphs. This seemed to correct the graphs (12 graphs including Flow Rate). But on September 21, it went back to displaying 6 graphs only with Flow Rate missing. The File\Preference\Waveforms still got 12 events checked. The Event Types got all parameters (including Fkow Rate) checked.

I would appreciate if someone throw some light on what triggers back to displaying 6 graphs instead of 12.

Note: I added SpO2 and PR graphs from the Pulse Oximeter Contec CMS 50F so that makes a total of 8 graphs as shown in the attached screenshot.

My flow limits graph for the DS2 is missing too.
The data is in the Overview display, just not on the Graphs.
Otherwise I seem to have 12 graphs

As far as I know, a Philips machine doesn't have a flow limit graph, a Resmed does only when it's in the Auto mode.

RE: Oscar 1.4.0 = DS2 Flow Rate waveform missing in Graphs display
Here is the update on the missing graphs with Philips DS2.

I am back to 12 graphs again for the past 2 days. I delay my update to see whether it really correct the problem. Two things happened during those days where the FL graphs were missing. First, the DS2 alert me with the problem in SD storage backup when I end the sleep session. The message flash was only momentarily and it missed my attention. Besides when I import the data to Oscar, I still got 6 graphs, minus FL. Second, the next day I forgot to put the SDcard back to DS2 the whole night. I realized the problem in the morning when it alert about SDcard missing. I quickly insert the SDcard back to the DS2, wear the mask and record more data for about 1 minute and end the sleep session hoping that all the data will be saved to SDcard. When I import the data to Oscar, I got only 6 graphs again. That is the time I posted this thread (ignoring the hardware SD card problems) and thinking more along the line of Oscar imports.

Now I am paying careful attentions to the DS2 SDcard massages and make certain that SDcard sits properly in the DS2 machine. I am a little concerned about the SDcard hardware problems as we are inserting the slot daily to upload the fresh data. Also to get access to the SDcard in DS2, we need to remove the humidifier container all the time. On DS1 it has an open access.

Finally, (maybe I need to make a new thread) I would like to request the ApneaBoard team to look into Bluetooth data import option like the DreamMapper App. Much grateful to the ApneaBoard team for all the great works. Cheers.

Please check with my Update I post today. Maybe it will help your situation.
