Is this a Windows thing? I'm not getting any errors on Ubuntu.

To reproduce you also need:

[LOGGING]
logging-format-style=new

The new style is about {} style formatting and the old style %f so pylint is confused about the old style being used when the new style is declared.

It seems

logging.warning( "The frequency is: {:.2f} MHz", 2.3 )

also raises a false positive with

[LOGGING]
logging-format-style=old
