Blue Tree ELD 59 minutes of driving showing

Upon logging in, I noticed 59 minutes of driving on the ELD, I had no idea how to get it off. Knowing that it would not be a problem on this trip, I went ahead and ran it . But the question still bugs me, how did this happened and was there anyway that it could have been corrected?

 

I swapped tractor and trailer with another driver. Logged out on the truck I left, logged in on the truck I stepped into. All this happened at a truck stop. I really do not see how this could have occurred. It really did not harm me in any way because once I got in, I was going off duty for several days,.
