Hi @Renato30, welcome to the Community
The "error" on the account is actually a verification block as you mention and in order to remove it, this verification would need to be completed.
Your ID was already checked and approved however the document sent as a "Proof of Address" was declined as the document was not eligible. What constitutes a Proof of address are utility bills, tax returns, Bank Statements or official government certificates dated within 3 months. The link below can provide you with a more in depth explanation over what are the exact requirements, please let us know if you have any further questions.
