Thanks for your post! I have reviewed your account and it looks like all of your current saved packaging settings has an 'Override Weight' listed. We are going to continue to update this feature and will support your request in the New Year to have the override weight applied to the individual packages
In the meantime, a solution would be to create a Saved Package with no weight assigned.
I appreciate you taking the time to share your feedback! We will continue to make improvements to this modal.
