C++ clang code style doesn't remember settings

The way to find the error.

Go to the Tools->Options...>C++>Code style section
copy "Qt(built-in)" settings
click "Edit..." button
go to the ClangFormat tab
change some option
(for example select AlignConsecutiveDeclarations as true)
then click Ok button in Dialog and another Ok in Options Dialog.

The style works, but if we open this settings to change another clang format option, we will see that AlignConsecutiveDeclarations became Default, and not true as we have selected before. And after changing another option we will close the dialog and will see that the first selected format option (AlignConsecutiveDeclarations) has lost and doesn't work.
