Hello,
Thank you for contacting Rank Math, and sorry for any inconvenience caused.
You can increase the Links per sitemap in the sitemap settings to remove the sub-sitemap.

That should fix the issue. Please let me know if that does not. We are here to assist.
Hi Anas! It solved the problem! Thank you for being so quick and efficient!
Greetings,
Marco
