Default reset_slots not working

When using in story file reset_slots like

## Generated Story 4798739145841452345
* intent{"Leistung": "bla"}
    - slot{"Leistung": ["bla"]}
    - action_bla
    - reset_slots

it resets not the slots…

hm, what happens? do you see an AllSlotsReset() in your debug log? the slots should have been reset, if you enter something after this event, do you see that the slot list is now empty?
