Thank you, Cybrosys Techno Solutions Pvt. Ltd., for your response. However, this issue occurs across all V18 databases. I have verified it in multiple Odoo databases on Odoo.sh and also checked on Runbot, where the same issue persists.

I have also noticed this issue as of a few days ago. No changes have been made to the database or contacts to cause them to be hidden. I had to manually remove the invisibility using studio to be able to see the fields. Hirav, were you able to get this fixed?

Hello,

Thank you for contacting Odoo Support. My name is Taj, and I will be your point of contact for this ticket.

I understand you’re experiencing an issue where the AvaTax fields on the customer contact form disappear. I want to assure you that this behavior has already been identified as a bug by our Bug Fix team. They are currently working on a resolution, although in some cases the deployment of a fix may take additional time.

I will continue to monitor the status of this issue and will notify you as soon as the fix has been released and applied to your database. Once deployed, we can verify together that the standard behavior has been restored.

If you have any additional questions or concerns in the meantime, please feel free to reach out.

Best regards,
