About: Some strings not translated

In the new About view (which, btw., is great) some strings seem to not translate. See the following screenshot:

"No description available.", "No rules available." and "No terms available.", "Contact" are not translated, even though they are in the German app.po file.

For "Features" there does not seem to be a translatable string at all. And "Send us an email: contactEmail" looks not correct
