This is what i've done
I made a Backup on HX Edit (V 3.10)
I updated the HX Effects to version 3.11 again.
Then perform a factory reset (be careful, will delete all user presets, IR's, globals): (hold down the footswitch Tap and 6 (to the left of tap)) , turn on HX Effects.
Wait for "Will reset Globals and restore stock Presets" an let go.
Do not restore your backup yet!
Test looper with the factory presets only. It must work then.
If so, restore your backup afterwards and test it again.
Now, everything works correctly.
