That's strange as I'm currently not using any automated parameters. However, the affected GUI elements are controlled in some way by send/receive messages. And the indicators magically appear somewhere in the process of editing and testing my devices.
Christian is right that's a feature, and the expected behavior from any parameter in Live. However in this specific example, I don't think you want the live.text's play object to be seen as an automatable parameter, if you set the parameter visibility to hidden in the object's inspector it won't be stored in the preset or the automation.
