The current po file looks okay to me, but the window is too narrow to display all of the text. (The “]†you see is actually the beginning of “1â€ÂÂ.)
As this window does not really obscure any other information I think it could be made wider by default.
EDIT: As to the question on why to translate the number: It is not the number per se that is translated (would be good if it was possible though, especially for languages not using the Latin script) but the whole phrase. Consider a language that uses counters or other grammatical words put after the number, for example: “Job Level: 10-levelâ€ÂÂ. (In other cases the number perhaps need to come first or something similar.)
