onepage checkout extension(s) / incorrect cart amount on order modification

Posting for Information and awareness only.
Faced similar problem as reported in issue no. 56. (with default opencart theme - v3.0.3.7)
From single page checkout, order was modified after cancelling the order (by clicking on the "x" mark on razorpay payment popup).
Upon confirmation of order again (after cart changes), the previously used / initially used cart value was being considered by razorpay in the payment popup window.
Module developers are investigating to fix the issue. I guess I cannot post the fix that may be provided as such changes are dependent on respective developers module.
Razorpay response was that they support only default checkout features of opencart.

For one-page checkout, when you are modifying the order via cart update etc.
If possible try to send a new order id for fixing this issue.
If you send the old order id again, then the same old order amount shall come.
