How to delete active Configurations in Web Channel Builder?

Hallo Community,

I'm a new-born in WCEM. I'm developing WCEM Applications in ERP Backend. The problem I have is, I cannot delete Applications I created. The system says, that this is impossible because a configuration is active. When I then go to the indicated active configuration, there is no possibility to delete it. Can somebody help me to fix this?

Thanks in advance
