Every time I do things in the customer list in Quickbooks 2020 that should have nothing to do with the display of the list, such as resizing columns, or switching between the customer list and the split view (where you see the transactions for an item in the customer list), the customer list itself switches from hierarchical to flat. Why? Clearly this is another bug in 2020. Am I alone in seeing this? 

Windows 10, latest update to Quickbooks Pro 2020 Desktop.

Remind me again why this software costs me more than $200 every 3 years?
