SmartCrawl: Strings missing in translation file

I'm working on the SmartCrawl translation for Dutch, almost done, but there are a bunch of strings not in the file. Also, some strings are translated but they still appear in EnglishWordPress version.

Unfortunately I haven't kept track of them all, I should have, but, one example I can think of is "Refresh" button in SmartCrawl's edit page meta box.

I think the SmartCrawl devs need to go over all the strings again and double check
