ADB appbackup gone wrong after rooting

So i recently rooted my device and made a backup with adb, using adb backup -all. After I successfully rooted my device I restored them using adb restore backup.ab. So it did work for some apps, for others it didnt. My Problem is besides that I have some apps twofold (?), somehow some appsymbols and widgets are locked on my homescreen. If I try to delete them It says "Unfortunately, Trebuchet has stopped.". I just want to get rid of this, I dont really care that much about my appdata. I am on CM13 btw.

Help will be appreciated.
