In Desktop Mode, changing a variable from the default seems to always work, but changing it back in the add-on interface will not actually change it, still unchanged after a restart. The config.json shows no change. Changing multiple variables at once can sometimes get them all to change successfully, but this is inconsistent, and I haven't found a pattern. The only sure way is to delete the config.json and start over.
