We added this notice in order to help non technical users reinstall the lost extensions after v2.4.13 update https://wordpress.org/plugins/unyson/changelog/

It is visible only when you have at least one extension compatible with your theme not installed.

You can disable it manually by a return; here https://github.com/ThemeFuse/Unyson/blob/v2.4.13/framework/core/components/extensions/manager/class–fw-extensions-manager.php#L3179
