Refactoring offers to add includes with wrong Capitalization and already existing includes

In a method in a newly setup GuiApplication I typed:

QFIleDialog (yes a capital I ... should be i)

Ok, how to fix the 'I' to become an 'i'?
Idea: Use refactoring:

1. Use Alt+Enter to ask for the include, that is missing anyway.
2. Use Ctrl+Space to let QtCreator fix the class name.

Ok, 1. gives me the option to add include <QFIleDialog> ... with an capital 'I'. I confirm adding it. It is marked with a "non portable path" warning. Cool.

Anyway, for 2. I press Ctrl+Space again (with my cursor still on QFIleInfo) and QtCreator offers me to fix it to QFileInfo ... I confirm. Yeah.

Ok, I remove the "non portable path" warning by positioning the cursor in the "include" statement and press Alt+Enter to have it fixed. Very cool. The waring vanishes.

Now I continue to add a static method ::getOpenFileName() after my "now fixed" QFileDialog.

As I want to have the return value as a local variable I press Alt+Enter again to choose the refactoring option.

But hey: It offers me:

• Add #include <QFileDialog> .... I already have this ... why is it presented here?
• Add #include <QFIleDialog> ... hey, with a capital 'I' again ... there is no reason to have this

I think it should not offer to have an additional #include <QFileDialog> and it should not offer a QFIleDialog to be included, too.
