That battery if authentic should be fine. Set your cell soft cut off to 2.7 volts. A bad connection from the battery will result with that warning as well as a low battery. Clean the threads anyway even if they look clean.
Clean the threads on the battery cap and it's corresponding threads, I suspect your problem is there. Also if using EScribe Device monitor you can see if you have a really big voltage drop on the battery (because of a bad connection, ect.)
Well you probably did the right thing by putting it backto the original setting. Being that it wasn't zero means they checked it at least on one. I'm going to have to call it a software flaw of sorts. I believe it came about with SP2. You could revert it back to a 2015 or January 2016 firmware to set it for your self but if there's not a problem I wouldn't bother. Most mods fall into the 0.004 - 0.006 ohm area.
Use the button circled in red. but with resister wire such as Kanthal the device will recognize it as such. No CSV file is needed for Nichrome or Kanthal. Your attached CSV file is of the type used....btw
I'm not sure what the problem is but the device does monitor board temperature and if too warm will cut off the charging. Sorry but I don't know what the numbers are. Check in Device Monitor what the temps are during charging and post it. Oh, pretty hard to do with a wall charger...duh On 2nd thought you can set the screen to show board temp
