I’m not certain about the missing translations. I saw a report from a German speaker who noticed the same thing. It may just be a gap in translation but not certain.
As for the fill+line, that functionality has now moved to the sublayer functionality. If you open the Cut settings for the layer, you can define any number of sublayers with fill, line, offset fill, and in any order. It’s quite flexible. So instead of a single “fill+line” mode, you create a fill sublayer, and then a line sublayer to accomplish the same thing.
