How to upgrade a deck?

After having created several saved games for a module I detected some shortcuts not well defined on the cards of a deck.
To solve the problem I hve in a first time adapted the short keys as expected and upgraded just after that the version of the module.
At the end and badly, in trying to use the “Upgrade Saved Games” I don’t see any impact of the definition on the deck. The old shortcuts are always visible and not the new ones.

Someone could help me to find a solution no requiring to recreate the saved games?

Many Thanks
