Creation of SAP Cloud Platform Business Application from template fails with error in Web IDE

Hello SAP Web IDE Full Stack and Cloud Foundry Experts,

I've installed the CF Builder in my space via the Web IDE Settings:

Then I create a project as described in Build a Business App by Reusing a CDS Model. The Project Details look like that:

But when I now finish the wizard I get the following error:

Could not start the build of 'test' because the Cloud Foundry settings are not configured for your project.
Go to Project Settings > Cloud Foundry, select your space, and click Install Builder.

But as mentioned above I already did that settings.

Best regards
Gregor
