Xcode 10 Error: Multiple commands produce for 'app' and 'appex'

I got the recently discussed "Xcode 10 Error: Multiple commands produce..." error, but for the resulting app and appex file of my project. Does anyone have an idea what this means. My project has one app and two extensions (only one is part of the error).

I know I can go back to the legacy build system, but I would prefer using the new and faster build system. Thank you for any help.
