Authors not displaying on sitemap

Hi guys. Hope you are well.

I have some authors on my website whose accounts I have created using the default wordpress method. However, since my website has many authors, I did not want to go make an account for all these authors (since they would not be using it). Therefore I added the your plugin. So i go to users > guest authors > add new to create a new author.

The issue is that yoast’s sitemap only displays those authors that have wordpress accounts and not guest authors. This is a real issue. I talked to yoast they said that the authors created using the plugin have a noindex tag but they are unsure if Yoast or your plugin is doing this.

Please help
