Hi!
As a reminder, if you set a min 1 on your fleet scaling setting, and leave your fleet online with no allocation, your project will generate usage, and will either consume your credits or generate costs you will be charged for. This is happening because the system keeps machines alive in case of an allocation, and is a regular function of our platform.
You can mitigate unwanted costs by either switching your fleet offline, or setting a min scaling setting to 0. We have added some extra messaging in our UI and documentation to make it extra clear.
