Product bundle not calculating the total weight of the bundle

I have created two “Items” and each item is “Maintaining Stock” and has a weight and a price assigned to it. If i create a “Product Bundle” and include the two items into the bundle then there will be no “Net weight” based on the two item weights be generated in neither the Quotation, Sales Order or Sales Invoice document.
Does the "Total net weight " even work for product bundles.
Happy for any thoughts and help on the issue.

ERPNEXT Version 14.51

Version 14 seems to got rid of the function to calculate the net weight of items in a product bundle.

Does anyone know if the function will return with V15 again or what can we do to calculate the weight based on the itemes included in a bundle
