When configuring SMG with a Global Attachment List or Global Pattern, attempting to save the Global Attachment List or Global Pattern without selecting any attachment list or pattern results in a warning message that a delete action is being attempted:
Please select at least one Attachment List to delete. Please select at least one pattern to delete.
The incorrect dialog text is being raised in the warning that a Attachment List / Pattern must be selected.
This display issue will be addressed in a future release.
When presented with the warning dialog, please select either an Attachment List or Pattern before clicking "Apply"
