Today I tested Ninja Clicky module v2.0 on Joomla 1.6. I noticed that this package contains an English language file, so I tried to translate it into Chinese language.
But, it can't be translated, because you used space characters in the parameter labels.
Module Class Suffix
You should use:
because Joomla 1.6 does NOT allo space characters in parameter labels and options, otherwise, those static strings can not be translated via language file.
I hope you will improve this XML file so that I can make a full translation.
And don't forget to edit your other extensions's XML files if you want them running on Joomla 1.6.
