Category name changes into Plural automatically

[GRuuuuu]

Hello, I want to mark the category name as it is...
Now it makes the name plural noun automatically like this image below.

In some cases, It makes very weird words.
How can I fix it?

Try setting

pluralizeListTitles = false

That should keep category names as you write them.
