You have set up travel insurance or another extra as an additional fee in Guesty, but your website checkout does not offer it as an optional add-on.
Why this happens. The booking engine only shows a Guesty fee as an optional add-on at checkout when that fee has the Upsell on your website option switched on in Guesty, with a description filled in. A fee that exists on the listing without that option is treated as a regular mandatory fee and never appears as a selectable add-on.
How to fix it.
- Open the fee in Guesty, under Financials > Additional fees, or directly on the listing.
- Enable Upsell on your website.
- Add a short description.
- Save.

Your website picks up the change on its next sync with Guesty. Once you have saved the setting, let support know and they can confirm the add-on is appearing correctly at checkout.
