Cannot add or change Antispam rule anymore

Question

Hi! 
 I've recently discovered that I can't change an existing or add a new Anti-Spam rule in my (non-MTA) XG 16.01.1 
 Whenever I try to do so, it just fails telling me "Unable to add scanning rule". It doesn't matter what kind of details I choose and it also doesn't seem to be related to the name or any other kind of string in that rule...

Oxident, 
 can you share a screenshot of the error? I am able to add both SMTP and IMAP policy with no issue. 
 Thanks

Hi Luk, 
 well, in order to provide you a "readable" screenshot, I've changed the admin interface's language from German to English and surprisingly, the problem disappeared! 
 So it only seems to be a problem with the interface language, after all... 
 Anyway, thanks for your help ;-)
