LibreOffice changes tipography when saving as word file

Checked in LO 4 and 5.

I create a new blank document with unaltered “Default style” (Liberation serif font). I save as Word document (.doc extension). When I reopen it, “Default style” font face was changed to “Liberation serif;Times new roman”.

It also happens when “Default style” is changed to “Liberation sans”; this time it’s changed to “Liberation sans;Arial”.

That annoys me.

Is there any way to deactivate this feature?
