Thread:Help talk:Extension:Translate/Can't find outdated text

I was asked to help with translation of Commons:Commons:Senate of Poland. Everything went well except that once everything was translated the polish and french pages claims to be 89% translated instead of 100%. See. It seems like something is 11% outdated but I can not find what and how to fix it. Also there is a problem with categorization. On Commons we never categorize language subtemplates, but this extension seems to do it, see Commons:Category:Wikimedia Polska is there a way to fix it, or is this something I should file a bug report about?
