Error in sitemap xml with Custom Post Type Permalinks

Hi everybody!
First we used your plugin since a while and it’s a must have ! Thank you for this !

I just have an issue with an other plugin… I use “Custom Post Type Permalinks” to have a specific link for my custom post type. I allready contact the plugin author about the issue with yoast but I don’t have an answer… Here is the post : https://wordpress.org/support/topic/yoast-xml-sitemap-error/#post-9446940

I want to have my taxonomy name before the post name.
So with this plugin I can do this in permalink structure :
/%custom_taxonomy_slug%/%postname%/

But in the yoast sitemmap xml I have :
https://www.sitename.com/%taxonomy_name%/post-slug/

It seems that Yoast seo don’t understand the tag %custom_taxonomy_slug%…

Do you know a way to do resolved this issue ? Do you know an other way to do the same thing ?

Sincerely
Boris
