Screenshot of the problem
Open the Area tab, then choose the Pattern button.
The pattern names in the left side selector that show up as a popup are not translatable.
These are coming from extras/source/palettes/standard.sop (see the Contents.xml in this zip) and were only added last summer.
I'll fix it soon.
