Hi There,
We have seen your website and we saw you fully customized the template with your own, also customized the orderform too. We think, you did something in a wrong way.
In this issue, we are unable to help you.
This is because, our template’s orderform doesn’t have any problem like this.
In this issue, you could use and test any of the WHMCS default orderform.
Best Regards,
ThemeLooks Support Team
