I have no clue how to resolve this. This label was generated today. I get the same issues with labels generated prior to today. I have sent this to chat but don't have much hope anyone will hop on and help me.
Thanks for being a part of our community and for reaching out. I see that you were able to work with our support team, are you still experiencing this behavior still or was it resolved?
