Thread:Support/Cache issue in LanguageStats?

Seems to be a cache issue in LanguageStats for hsb. MediaWiki extensions group shows 208 untranslated messages. The percentage for translated messages is 97.50 %. Yesterday the number of untranslated messages was the same but the percentage for translated messages was higher, 97.51 %. The same issue is for dsb. Have been some messages deleted or are there hidden untranslated messages?
