All Shopper fields containing the word "invoice" cannot be saved!

[manolis_max]

Hi everyone,

I'm using the latest VirtueMart version (3.4.2) and I'm facing this issue: I realized that all user field containing the word "invoice" (invoice_vat_number or vat_number_invoice for example) cannot be saved on checkout or user account.
I changed the names (from database) deleting the word "invoice" and everything worked again.

Has anyone noticed the issue?

Thank you in advance.

Regards,
Manolis
