This usually happens if Jetpack detects an identical site with a different URL. Do you have a staging site with a different URL, or have you recently migrated the site?
To prevent this from happening, we recommend making sure Jetpack is in staging mode on any staging sites and disconnecting Jetpack before migrating a site.
If you have a separate staging site, could you please post the site URL here so that we can have a look?
If you want it to remain private, you can also contact us via this contact form. If you choose to reach out directly, please include a link to this thread.
Thanks!
