Sonoff smart plug with power monitor data went missing

I hope somebody reads this…
So the end of the month happened, monthly graph switched to April. Since I can’t look back at March in the bar graph, have to download the csv for each of my 4 devices to get data for March 31. I’m attaching the csv files downloaded for the first 2 devices. The other 2 devices had the same issue when I downloaded the csv’s for them.
First device was downloaded fine, Here is the March part of the file…

when I downloaded the second device the data was corrupted. Here is the March part of that file. Seems to be mixing the csv’s together, repeating part of the first file in to the second file. See the tail end where March 30, 31 and April 1 repeat in second file. This is likely what caused the issue that prompted me to start this thread.

I don’t know how this happens, can someone fix it so it doesn’t happen again?
I see the filename has been changed since the last time I needed to download them. I wonder if the filename needs to be unique for each device?
