Incomplete Author Sitemap

Hi, first of all, congratulations to the plugin!

In my site there are about 1100 users, but in the sitemap only 2 appear.

There are 4 administrators and 3 authors who publish frequently in wp-admin, the other users “subscribers” publish via frontend.

I did a test, excluding the sitemap option for admins but it does not work, it always shows only the 2 users (these two users were the first to be created).

Look: https://www.autocustom.com.br/sitemap_author.xml

Could you help me figure it out?
Thank you
