Hi @birken!
Thank you for reaching out back.
i am using Flexible Checkout Fields plugin by WP desk as i need some extra information from customer. maybe that is the problem?
It could be. Sometimes, an outdated or malfunctioning code could be interfering. To be sure of this, you could try performing a conflict test as recommended by @shameemreza earlier.
To do it, temporarily switch your theme back to Storefront, disabling all plugins except WooCommerce and Stripe, and then check again if the issue persists.
If that solves it, reactivate the theme first and check again. Then, reactivate your other plugins, testing each until you find the one causing conflict.
If you cannot perform a conflict test on your live site, we recommend creating a staging site using the WP Staging plugin.
You can find a more detailed explanation of how to do a conflict test here: https://woo.com/document/how-to-test-for-conflicts/
it seem my default WooCommerce checkout don’t show filed for customers address, post code and country.. where do enable that?
By default, at checkout, WooCommerce shows fields like address, country, region, and postal code in the Shipping Address section. The image below shows how these fields display on my test site using the Storefront theme.

If you can’t see these fields displaying in the Shipping Address section of your checkout page, it could be something related to your theme not displaying it or a conflict with another plugin. Please try changing your theme to Storefront or performing a conflict test to see if it helps to solve the issue.
Let us know how it goes!
