In the options tab of your browser extension you set the default match detection. And so if in your entries the detection setting is “Standard match” they will use the setting you set in options as default.
It’s not a bug. In your case “Standard match” in an entry means “basic domain” because this is what you set as your standard match detection. If you set your standard URI detection to “Server” in the extension so “Standard match” in an entry means “Server”.
