In certain categories one article becomes at top in block group for his letters
(for example, Baa Bbc Bcb -> Bbc Baa Bcb )
and the block letters becomes ahead of all the blocks of other letters
([A] Aaa Abc Acb [B] Baa Bbc Bcb [C] ... -> [B] Bbc Baa Bcb [A] Aaa Abc Acb [C] ... )
such wrong sequence is still displayed in the categories
example category 1:
https://ru.wikipedia.org/wiki/%D0%9A%D0%B0%D1%82%D0%B5%D0%B3%D0%BE%D1%80%D0%B8%D1%8F:%D0%A3%D0%BC%D0%B5%D1%80%D1%88%D0%B8%D0%B5_11_%D1%8F%D0%BD%D0%B2%D0%B0%D1%80%D1%8F

example category 2:

correct order of letters in the alphabet:

I tried ?action=purge and Null edit for articles and categories - without result
I tried to change the template, which adds a category, to this category writing this category in wikitext and removing the template from the article - without result
Then I tried ?action=purge, minor and Null edit for articles and categories - without result
I turning back template - without result
if delete a category from the wikitext - article disappears from the category
if then write a category in wikitext - аrticle will in normal right place in the category
At first category appears as follows: date added to Wikidat and article template generates the category through the Module (sorting there is not provided, just a [[Category:Died in +Wikidata+ year]]), then it can be seen in the article. Maybe the problem shown itself somewhere along this path.
(article (one of those that puts at the beginning of the category) that I changed and that was displayed incorrectly
