Currently the term "Kopier" is automatically applied to layers to translate, for example, "Layer 1 Copy" into "Lag 1 Kopier". This is an incorrect verb form of "copy," where the noun form "Kopi" should be used in Danish instead, i.e. "Lag 1 Kopi" alternatively "Kopi af Lag 1" (meaning "Copy of Layer 1.")
This seems to occur in Adobe apps translated to Danish in general but is just very prominent in Photoshop.
