Hi,
Thank you for reaching out. This is Joel Porselvan from the Customer Support Team.
It sounds like you might be trying to hide products in the checkout that are already in your cart. If that’s the case, you can activate the “Smart upsell products display” feature.
To do this, navigate to the settings page, select ‘campaigns’, and enable the “Smart upsell products display.
Here’s a screenshot for your reference: https://nimb.ws/pXbCouK
Or, if you’re looking to remove the offer on the checkout page when the Upsell offer is added to the checkout page.
We have a useful snippet, here is the snippet: https://gist.github.com/AnanthFlycart/1e2fb379042d423e4c4d0f9320bccbfd
You can add it via the code snippets plugin.
Here is a guide that might be helpful:

Kindly check and let us know if it helps!
Regarding the issue where the ‘Add to Cart’ button is not appearing on a single product page after adding an offer:
If you’ve tried using the [cuw_cart_upsells] or [cuw_checkout_upsells] shortcodes on a single product page and they didn’t display as expected, it’s important to note that these shortcodes are specifically designed to show upsells on the cart and checkout pages.
If you require further assistance, please open a support ticket at UpsellWP Support. We’re here to help!
Thanks,
Team UpsellWP
