Issues in 2 Checkout parameters passed by opencart platrform

Hi There OC Team:
I would like to ask your help regarding the parameters on 2 Checkout payment module, when my customer is about to process credit card payment the parameters submitted to 2checkout payment gateway is only amount but its not detecting my default currency code AED. My site is running AED Currency. https://thelabstores.com however when customer is about to pay the 2 checkout payment portal only detected USD currency code from our site.

Any help would be highly appreciated.

Thank you!

Take note: Im Running Opencart 3.0.2.0 version

Waiting for any response, ive tried all other forums posted but not even 1 solution works...Thanks

What happens with other Payment methods? Is it a site, template or payment module problem I wonder. Try enabiling Paypal Standard and place an order right up to the Paypal handover and see what happens. There's no need to actually put the payment through.
