Automated receipt generation for sellers exempt from VAT registration

Hi, I am UK based seller. I have received the VAT exemption for UK from the amazon. But when i am going to the automate receipt generation then i am not finding the button to “Declare VAT registration exemption”. It was giving me alert message saying:

You are not eligible for automatic receipt generation.

According to our records, you do not meet the Terms and Conditions of the VAT registration exemption. Consult your tax advisor to determine your EU VAT registration status and complete your tax settings.

I have no intention to sell anything outside UK in other EU states. I already turned off the other market places by setting them inactive in holiday setting.

I also removed the other countries from Building Internation listing. Also i was automatically enrolled for the B2B for other countries that also i unenrolled.

In fulfillment by amazon also i disabled the "List your products across Europe".

But still getting the same error, dont understand what setting i am missing or what i have to ...

Please help and guide me..

Thanks
