Default build directory setting is ignored

When I create a qmake project or add an existing project to Qt Creator instead of the default build directory setting (under Build & Run / General) the directory that was used when the last project was added is set as default.
When adding a new Kit to a project the path from the setting is used.

It is easier to select the last used build directory from the lineedit completion, than to manually type something like

../build-%{CurrentProject:Name}-%{CurrentKit:FileSystemName}-%{CurrentBuild:Name}

so I think this should (again) be the default.

If you leave the directory empty and click on "Configure Project" the default build directory is used.
