Setting a default filter for Calligra Words opening docx

I’m trying out Calligra Words as my word processor and want it to automatically open docx files as the latest Microsoft Word version. I can’t find a way to configure that. What happens now when I click on a docx file is that Calligra Words opens up asking me to choose a filter from the following list:

  • Applix Words document
  • Microsoft Works document
  • ODM document
  • ODT document
  • ODT template
  • Plain text document
  • RTF document
  • Word 2007 document
  • Word 2007 document template
  • Word document
  • Word document
  • Word document template
  • WordPerfect document

How can I make it default to “Word document” without asking every time (and what’s the difference between the first and second “Word document”?

Dolphin knows that the file is of type Microsoft Word, so why doesn’t Calligra Words know that?
