For example, this issue happens if you create your company with English (Ireland) Region settings then create transactions with Irish tax codes. You then amend your tax codes to UK settings and change your computers Region settings to English (United Kingdom).

If you then upgrade to V33, which converts your data, your VAT region is Ireland. This is because you have Irish Tax Codes within Configuration and you have transactions that use these codes.

Your software will show Irish VAT Schemes in Company Preferences and the VIES Return option in the VAT module.  

This issue can also happen when you create your company with English (United Kingdom) Region settings and create transactions with UK tax codes. 

To resolve this, you can change the country in your software and update your tax codes.
