When changing a deck’s config to another, the config DR setting doesn’t change to the new selection. For example:

Config A has DR 90%
Config B has DR 85%

Deck X is currently using config A (and using config-level, not deck-level DR)
Edit Deck X, change config to B.
The config’s DR setting in the config editor remains 90% (it didn’t change to 85% in response to switching to config B)
Upon saving, config B’s DR is changed to 90% which is unexpected

This behaviour can cause people’s configs’ DR setting to get accidentally changed. The config-level DR in the editor should change according to the active config selection.
