Error when trying to modify addresses in Order page - BO

[C4rt4lytic]

When I try to change the address (both shipping and billing) of a back office order, paid with "cash on delivery", the shipping costs are retracted.
Even setting on Prestashop in the settings "Shop Parameters"> "Order Settings"> "Recalculate shipping costs after changing the order" on the value NO, the fee is no longer calculated in the shipping costs.

I tried to replicate the same error with a different payment but only "cash on delivery" has this problem.

I have the same problem with cash on delivery fee disappearing after edit order in BO.
Presta v. 8.1.7
PHP 7.3.33
modul Cash on delivery with fee (COD) PLUS v. 1.1.9
