I accidentally deleted a few favorite lists on PC but thought no problem, just upload to PC from scanner. Every favorite list was prompted in Sentinel that the scanner & PC were different. Well very well could be. After rechecking versions, firmware and loading current database just for the heck of it I tried to upload back to PC to see what happens. Same thing, get prompted that the two are different. Both PC and scanner have identical databases & favorite lists. Why do I keep getting prompted that they are different? I rechecked again and found both PC & scanner identical. There are choices on prompt to skip the favorite list your on or all of them if you want but I'm not sure why this happens. All is working fine but I think sofware may just do this by default. Can anyone explain or have the same problem?
