C++ Code Style Custom settings import - Wrong import of "tabs and indentation"

When I import a C++ / code style / clang format, the settings for tabs and indentations are not adopted by the file. The ‘default’ QtCreator settings are set.

Extract from clang-format file:

   <value type="int" key="IndentSize">2</value>
   <value type="int" key="PaddingMode">2</value>
   <value type="bool" key="SpacesForTabs">true</value>
   <value type="int" key="TabSize">2</value>

Imported settings in QtCreator:

Exporting the clang-format settings seems to be correct.

I use the ‘Build-In-Indenter’ for exporting and importing.
