Question about WooCommerce Subscription

You’ll need to review the docs for WooCommerce Subscriptions directly on this. From the screenshot, it looks like you’re adding the one-time fee to the product rather than the cart checkout. There’s a section in the Subscription Docs that talks specifically about the recurring fees aspect and what code to change.

Unfortunately, the forums here are for WordPress itself and not the WooCommerce plugin, so you’ll want to check their docs and support team directly.
