Hello @Eclipse1 and welcome to our customer community. Thanks for posting.
The Base Unit indicator should be True for the lowest level of your hierarchy only please. You can fix that by going into the lowest level of your hierarchy and changing it to True. It should be False on all other hierarchy levels, please. Here is an article explaining indicators: Indicators in Item Management
The link quantities should match the Total Count attribute on the highest hierarchy level and it should be 1 on the lowest hierarchy level. Here is an article explaining how to add the hierarchy information successfully for your items: Total Count of All Products - Qty Next Level Items - Hierarchy Link Quantities
Please let us know if this was clear or if there is anything else we can help you with for this request. Thank you!
