I just realized you said you were using the original MobileSheets on Android and not MobileSheetsPro. Going from MobileSheets on Android to MobileSheets on Windows 10 is a lot more error prone than going from MobileSheetsPro->MobileSheets due to the huge number of differences, some of which aren't easily resolved when going from the Android OS to Windows 10. Without a backup file, I definitely won't have any way of looking into this I'm afraid. Hopefully you have things in a working state now and sorry I can't do more.
