The catalogue entry Quantity served both the pattern dialogs' number of instances and the motion study's plotted quantity. Nine locales had translated the second meaning, so the rectangular pattern dialog showed e.g. "Größe" above "Anzahl 2" in German. The motion study's row now reads motion.plot_quantity (a pending file that keeps every locale's previous word there). Quantity takes each catalogue's own ui.quantity text, which the "Quantity 2" row already shows; nothing is newly translated. The glossary lists Quantity under words with more than one meaning.
