Fixed in build 8007. There was a bug that prevented the software from reading your last settings from preferences.ini correctly. Only happened when you had some of the optons checked (not all and not none).
By the way, the list in the config app says “Default Tasks” because it is used in places that do not have a config setting of their own (like the DB Sync dialog).
When you sync a storage for the first time, it will use the same options as defined in the config. But after that, the sync dialog will remember the last options you used for that storage.
