Tax Classification Code Not Showing in AP or AR

Hi Experts,

Maybe you could help me on this.

Last month i create a tax regime along with the tax rates and all. I am using a Global Configuration owner for the taxes.

the tax rates are shown in the AR Transaction Line Tax Classification Code field and also shown in the AP Invoice Line Tax Classification code field.

When i click the Tax Details on both AR & AP, the tax rates also shown in the Tax Classification Code fields there.

Then, recently, i add up a new tax rates into the same tax & regime with the exact same setting.
