Hello,
Thank you for contacting us and sorry for any inconvenience that might have been caused due to that.
When that happens it means that the theme you are currently using doesn’t include support for this feature from the WordPress guidelines: https://developer.wordpress.org/block-editor/how-to-guides/themes/theme-support/
You would need to get in touch with your theme provider to update their code and include support for that.
Hope that helps and please don’t hesitate to let us know if you have any other questions.
Thank you.
