The two example servers "Revspace sensors" and "mqtt-analyzer mosquitto example" will reappear if the usage of iCloud is activate. It works fine if iCloud is disabled.
For MQTTAnalyter you can specify in Settings -> Apple ID -> iCloud whether it is permitted to use iCloud. If I do so and delete any of the examples from the list of servers, they reappear in the list whenever I restart the app. If iCloud usage is not active, everything works fine; after removal the examples remain away. As soon as iCloud is enabled again, they reappear in the list.
