Detected overridden config

Could anyone shed any light on why "detected overridden config - adding "{FYsMb}" suffix to name" has started showing up in my rclone log files? The commands still work and function as intended, so I don't have any issues, just curious as to why that has started appearing, the only thing I have done is update rclone to the latest version.
