Speed Editor: button to delete a clip in the timeline ?

Hello, I have received the new speed editor.
first a big praise, this is a great device.
I have never selected and cut so quickly.

Now my question:
If I want to delete a clip again on the cutpage (Not the edit page!) in the timeline... which button do I have to use for that ?
I have not found one.
Or is a special workaround needed for deleting a clip on the timeline (cutpage) ?

another short second question:
Is there a german manual ?
On the "welcome card" it says something about it, but for download "only" the english one is offered.
Greetings Daniel

Update:
after updating the Speed Editor and Resolve to version 17.2 it works.

The following question remains:
is there a german manual?
