If this problem is not resolved, it is necessary to unset the item "Consumption tax group" in the customer master record to avoid operation.

However, if you do this, the initial value will not be set for the consumption tax group when registering a sales order, so you will have to enter it manually each time. Therefore, if you have a large number of sales order lines, it will take a long time to enter them.

The end users I am responsible for register approximately 100 sales orders every day. per user if each sales order has 20 lines.

5 seconds x 100 x 20 = 2000 seconds → 33.3 minutes loss.

Therefore, I would like to request that measures be taken to address this issue.
