Post Tags Not Displaying in Sitemap

Hello my yoast sitemap is not including post_tags for some reason. https://prntscr.com/rd2wvx

I have made sure that tags are turned on for the site map.

I have another tag plugin for page_tags but I have used this with many other wordpress sites and yoast does not have any conflict with this ever.

I do have a large amount of tags on my website so I am not sure if this is the reason. Is there a limit to the number of tags yoast will display in the sitemap?

If there is a maximum anmount of tags then why is yoast not displaying any tags at all?

I do not want to have to use any other plugin but yoast and I do not have this issue with any of my other websites using the same setup.

Please advise.

Regards
Peter
