Ohhh. That's probably your issue. Apps are stored in a separate manner on lollipop and older Android versions (the lables, breadown of apk etc are all different) so that's why Titanium and Helium are having trouble restoring your backup files. I'm sorry I can't help much with that since none of my rooted devices are currently using Lollipop but I'm pretty sure there would be a workaround for your issue (try the xda forums. They are ingenious with this type of stuff).

Good luck :)
