I can repeat the problem.
After I start a new drawing, I can right-click on Layer 0 which gives me Layer_1. When I right-click "on" Layer_1, I get a new layer number, 2, preceded by the foreign characters: 慌敹彲2. Maybe they're farming out the development work to GstarCAD. If I right-click in an empty area in the DD palette and choose "New Layer", then I get a proper name; Layer_2.
