Unable to calculate tax automatically.

After tax rate is configured, tax cannot be calculated automatically.
When configuring output tax in ESP VAT, if [Tax Juridication Code] is selected in the tax rate setting, the tax on invoices receivable cannot be calculated automatically; if [Tax Juridication Code] is not selected in the tax rate setting, the tax on invoices receivable can be calculated automatically. Why? Does it matter if you choose this [tax judgment code]?
