Hi,

Try the following steps,

- Open the rental product form (Sales → Products → Rental tab).

- Check the field “Padding Time” (or “Safety Margin”).

- If it shows 6, update it to 0 or 2 as needed.

- Save.

After that, new rental reservations will respect the product-level value.

The 6-hour buffer you’re seeing isn’t coming from General Settings anymore, but from the per-product rental configuration. The global setting only applies when creating new rental products, it doesn’t retroactively update existing ones.

Hope it helps

The Default Padding Time in Rental -> Configuration -> Settings --> Rental specifies the default value for newly created products only.

Once a Product has been created, the Security Time (to be found i.e. via Rental -> Products -> *choose any rental product* --> Tab: Rental Prices -> Reservations) will not update automatically anymore. You will have to adjust this value for existing Products manually.
