Thread:Project:Support desk/Category Sorting after update

After updating from MW16.5 to MW17 it seems that the sorting in category pages is broken. There is one article that sorts under A, because I have edited and saved that article. All other untouched articles are not sorted on that category page, but appear under "D". Any suggestions?

I already have run maintenance/populateCategory.php and /maintenance/RefreshLinks.php without success. Is there maybe any extension, that would touch or save each article that exists in the wiki?

Thanks a lot in advance
