To Add to Brian’s response- If your Take Bin Handling setting in device configuration is set to find, it will not prompt for the bin change confirmation when the same bin that is on the line is scanned. However, if you scan a different bin it will throw an error no matching line found. At that point, you would use the change bin menu option to change the bin on the line. It sounds like your device configuration might be set to override with prompt, which will ask for confirmation regardless of it matching on the line.
