    Hi Ruppert Marketing,

    Hope you are doing good today. :slight_smile:

    What you are seeing is a warning message, and it doesn't appear to break the plugin. The message appears only when units are set in drafts, setting the unit to 'live' state should remove the warning message. Please check, and confirm.

    Please let us know if you need any further help. Have a nice day. :slight_smile:

    Kind Regards,
