Selected shipping method reset after cart update

[keep2000]

Hi,

I've installed Joomla 5 and Phoca Cart 5.0.2 along with the demo data. I also added the Zasilkovna plugin and configured a shipping method for it.

Everything works fine, but I noticed one issue:

When I select a shipping method and click the "Save" button, it gets stored correctly. However, if I then modify the cart (e.g., change a quantity and click "Update" for a product row), the address fields are preserved, but the selected shipping method is reset. If Zasilkovna was selected and a parcel locker had already been chosen, that also needs to be reselected.

Is there a way to preserve the selected shipping method and parcel locker after updating the cart?

Thanks in advance!
