Too many possibilities, can you please post your complete project, so that we all can have a look at all of your settings. To do so, use
Creator->File->Create Workspace Bundle (minimal)
and attach the resulting file.
in the meantime i found the answer:
Described on page 37 in the Pins datasheet --> Some devices, such as PSoC 4000 series do not have Port Adapters and this limits some pin features.
In this case i have to use my CY8CKIT-042-BLE to test it again.
