I'd just exclude that folder from Onedrive. The config files are constantly being updated by the game, for good reason.

Most people don't know when you do /isearch to search your retainers, those local log files contain that information needed for it, not a poll of the retainer on the servers. Every time you fetch your retainer the game constantly updates the store inventory to your PC so it can use that search cache. Rarely the game will say it has no confidence of your retainer inventory with answers of ??? but that can happen when it can't save the file.

Basically, just block onedrive from backing it up. Besides the real character/system backups should be uploaded using the game client.
