Cannot delete domain DNS after Package termination

Hy guys!

I've a bit of problem whit my WHMCS system. When I terminate a hosting package in WHMCS (whit the "Terminate" button), the system say:
"
Module Command Error
An unknown error occurred
"

The termination process fully occured, but the domain DNS doesn't deleted after this "termiante" process.

For few minutes, I see the account () in the "List Accounts" menu in WHM, and I see the account in the "Terminate Accounts" menu in WHM. After few minutes, I can't see the account in this sections, but the DNS is available in the "Edit DNS Zone" menu.

Do you know anysolution for this problem? Why the DNS cannot deleting, when I click "Terminate" button?

 

Hello!

Thanks, I found "cPanel Extended Center" at my "addons", and the "Module Settings" option at the "Edit products" cannot load. So I write to ModulesGarden about the problem whit their addon!
