If you put all value to "0" you will loose the data
If you enter the data instead of the zero you will safe old data
Option is to use only timelog and leave the low, high, gas value for day, month, year, cons out
If you upload the files you do not create a new device, but only update the program
I do not know if you have acces to the log file to see which variable it is blocking
