[Windows] issue on displayed language

on latest builds i see that the automatic translation of Kdenlive (at first startup) is partial

for example i'm' starting kdenlive on an italian OS... and on the language selection is correctly set "Italiano" (i made no changes) but seems that the only translated "part" is the bottom of this window.

Eugen, can you confirm that?

also the "color theme" names are translated (and the view has wrong colors for this: #400 (closed) )
