Key Influencers visual not working as expected with Conversion Rate measure

Hi,

The Key Influencers visual is telling me "No influencers found" when I expect there to be an influencer, so I put together a simple example to highlight the problem so that maybe someone can help me understand what I'm doing wrong.

I'm expecting the visual to report that Group "A" is a key influencer for increasing both the "Conversion Rate" (measure) and the "Score" (column) -- because I've configured the data such that these return the same numerical values when I segment the table by Group -- but the Key Influencers visual doesn't report any influencers when I analyze the Conversion Rate measure.

Here's what my single data table looks like:

Here's a table visual showing the results of my measures:

Note: The value of "Score" is 93 for all Group A users, and 70 for all Group B users. I purposely set these values to match the calculated conversion rates for the groups, which are 93% and 70% respectively.

The Key Influencers visual successfully finds that Group A is a key influencer when I analyze Score:

But it doesn't find any key influencers when I analyze Conversion Rate:

Can someone please help me understand what I need to change so that I can get the visual to work with my measure?

I've uploaded the .pbix file here for reference: https://d.pr/f/YTqdgy

Thank you!
