VAT ID NUMBER- Problems on Booking extranet

I got a VAT number from the tax office. And when I wanted to enter it in the section Finance - Data on VAT number, the question arises: Do you have a VAT number? As answers, the answers YES and the answer I HAVE, BUT NOT REGISTERED FOR EU TRANSACTIONS are offered. As I received a VAT ID number from the tax administration, I clicked the YES option, then entered the number, and I received an error that the VAT ID is not valid. I checked the validity of the VAT number in the European VAT number database and everything is fine. When I clicked on the option I HAVE A VAT NUMBER BUT IT IS NOT REGISTERED FOR EU TRANSACTIONS, then the VAT number is accepted. For my mother's accommodation, I also asked for a VAT ID number and I could normally enter it under the YES option, which was not possible for me. Please check what it is about, because it turns out that I have a VAT number, but it is not registered for transactions in the EU, and I have a Decision of the Tax Administration which issued me a VAT ID number and which is valid.

I dont know what to do? ://
