Changes to encryption settings, including changing the password, will require a new Full, which Reflect will create even if you request a Diff/Inc to continue in an existing set. That’s a relatively new change, requested by yours truly.
The previous behavior was that the set’s settings would persist for all backups in the set. So if you updated the definition file and continued making Diff/Inc backups, those new settings would be ignored in favor of the pre-existing settings for that set, until you manually created a new Full that would then use the current settings of the definition file. (The exception was merely changing the password, which caused subsequent Diff/Inc backups to fail completely because the new password would unusable for decrypting the existing backups, which made it impossible to append to that set.) Additionally, back then the log showed the current settings in the definition file, even though those weren't necessarily the settings actually used for that backup in this scenario.
The overarching principle is that encryption settings, along with some others, are held constant for all backups in a set. The only difference is how settings changes are handled.
