When adding files to groups of a QBS-Project, state name of the group instead of name of the QBS-File

Consider a simple QBS-Project that contains a group item:

import qbs

CppApplication {
type: "application" // To suppress bundle generation on Mac
consoleApplication: true
files: "main.cpp"

Group

}

When adding a new class to this QBS-Project, the new-file-wizard offers to add the files to the qbs-project on the last page. I can even select to which group the files should be added. But the dropdown does not label the groups according to their name, in my case "CoreFiles", but labels the group like the toplevel qbs-file. See my screenshot of add-class-wizard.png that shows two times the name qbs instead of "CoreFiles" for the highlighted group. In contrast, the qbs overview labels the group correctly.
