Hello,
Thanks for contacting us, and sorry for any inconvenience that might have been caused due to that.
Let’s first clear the cache and see if this resolves the issues.
1. Flush the Sitemap cache by following this video screencast:

Even after following the above steps, didn’t resolves the issue, then we might need to take a closer look at the settings. Please edit the first post on this ticket and include your WordPress & FTP logins in the designated Sensitive Data section.
Please do take a complete backup of your website before sharing the information with us.

It is completely secure and only our support staff has access to that section. If you want, you can use the below plugin to generate a temporary login URL to your website and share that with us instead:
https://wordpress.org/plugins/temporary-login-without-password/
You can use the above plugin in conjunction with the WP Security Audit Log to monitor what changes our staff might make on your website (if any):

We really look forward to helping you.
Hello,
I have updated the sensitive data as requested. Can you please check further?
Thank you.
Hello,
The taxonomy you had for the CPT was created with incorrect arguments and the sitemap was not able to fetch the URL data from the database.
We have created those categories by mimicking the same methods as the main theme was creating the “Services” and the other CPTs and the URLs are now being detected correctly on those taxonomies as well.
Don’t hesitate to get in touch if you have any other questions.
Thank you very much,I really appreciate your help with this considering it is outside the scope of the plug-in.
