sonarqube: sonar.test.inclusions results in sonar.exclusions

In "sonar.properties" I include some test-files with sonar.test.inclusions=**/myTest/**.

When I run an analysis, I get the included TEST SOURCES as well as excluded source files:

 Excluded sources:
 **/myTest/**
 Included tests:  
 **/myTest/**

My Question: Why do I get the included TEST SOURCES automatically as well as exlcuded source files?
