on meta.wikimedia.org, on Special:AggregateGroups some settings have been made that are not reflected on Special:LanguageStats/nl
See screenshots for comparison.
(at least) two inconsistencies are visible here:
A. "Fundraising 2012/Translation/FAQ" is part of aggregate group "Fundraising 2012". However, it is not collapsed by default in "Fundraising 2012" on LanguageStats.
B. Three pages starting with "Legal and Community Advocacy/" are part of aggregate group "Legal and Community Advocacy". However, they are not collapsed by default in "Legal and Community Advocacy" on LanguageStats.
