IT WORKS NOW 
The end of Dec I was using 1612.7 and today I updated to 1612.9
Using 1612.9 I was able to use the Custom mileage reset on my Windows laptop.
I had the unit set to miles.
I did not send a data log since it worked. Let me know if you still need a data log.
Thank You
Is the RS still available to you so you can continue to work on the problem?
Unfortunately, no. But, I'll have a look and see what could have caused the result you are seeing. I guess you won't be able to send us the application logs for the time when this happened, since it was more than a week ago. When you get another chance to re-run the function, could you please send those logs so that we can see what went wrong?
Can you remember at all what specific values you tried with the custom reset?
