Information about bug
In the Customer DocType, the ID (name) is always derived from customer_name, even when a Naming Series is configured. As a result:
Customer ID and Customer Name are effectively the same value.
The ID column is always shown in the Customer List View.
The ID column cannot be removed or hidden using List View Settings or Customize Form.
Since ID duplicates Customer Name, it adds no additional meaning and only clutters the list.
This behavior is confusing from a UX perspective because:
ID looks like a separate identifier but contains the same value as Customer Name.
Users expect either a meaningful, configurable ID or the ability to hide it.
