Is this a bug in the documentation for
"fine.OperationRatios.ROE.OneMonth"?

I believe it is. I have found when i use .Value i get the current values using the other .qualifiers it can be hit or miss. I come from the Quantopian camp which i think you did too and this is an area that Quantconnect needs to document better.

Hi Vladimir and Frank,
That is an issue with our docs. I've submitted an issue request here.
Furthermore, this post provides a great method for figuring out what fields are available for a fundamental field.
Best,
