A telemetry log error, no DataFlash Logs and some other questions

So I’ve been having some issues with my Intel Aero RTF drone and some of my recent telemetry logs give me an error when I try to graph them. I have tried converting them into CSV and text files to run in other programs and none of them are able to graph. I have posted a screenshot of this error!

I tried to download DataFlash logs and it does not appear to have written any and I am unclear why it wouldnt.

I clicked on a checkbox called testing screen. I was unable to find anything in the documentation talking about this feature and what everything means. Those red boxes don’t look very good to me.
