Hi,
Thank you for your question!
When you save a text with contour frame (and/or background fill) as a Label, the contour is broken down as polyline. Unfortunately, because of this process, the contour frame loses its connection to the actual text box. For this issue, I am very to say there is no workaround for it, as it is the limitation of the feature, as it was meant to be a basic custom label only.
For your second question, this is an easy one: you can choose the insertion to be at the pointer in the Label Settings, go down to Symbol Label Settings tab, you will see the Reference Point selection.
Here you can choose to insert at the pointer!
I hope I have answered all of your questions. Let me know if I can help you any further in this situation. Thank you very much!
Best regards,
Minh
