Current message is "$1 {{GENDER:$2|removed}} $3 from translation" and I think to message is not correct. Message should be like: "$1 {{GENDER:$2|removed}} option of translating for page $3" or something like that.

For the records, de says "from the translation system", cs also says "from translation", fr says "from translations to do".
Thanks! I think to correct message is: " $1 {{GENDER:$2|removed}} $3 from the translation system". I will make patch now.
