Code editor shows semantic, lexical or preprocessor issues when opening a qmake application

See the attached screen shot of widgets/widgets/analogclock.pro project opened.
There are semantic, lexical or preprocessor issues shown in the code editor.
The applications do build however and can be deployed to a device, but when stopping the example, application output says that appcontroller crashed.

Environment: B2Qt 6.3.0 toolchain, Qt Creator 7.0.1 (based on Qt 6.2.3)
