Hi Kupsol,
If the state of the radio button is in-fact saved, then it must be using data from a field to determine its state. You’ll need to check your OnScreenLoad actions for how the state of the radio button is set when a record is loaded. This should show you which field you want to filter the report for.
Moving forward, I’d recommend using a Yes/No field and dragging it directly onto the screen instead of a radio button. It will appear as a checkbox instead, but will help to eliminate confusion. I hope this helps.
