AWS Quicksight Q's why question help

Hi,

I am using AWS Quicksight Q to analyze a dataset. When a why question is employed with average aggregation function (e.g., "Why did value drop in 2020?"), the highlight of the result is wrong (e.g., %DIFF -75% drop when values are 61650.19 vs. 53150.14. Please see the attached image). If the same question is asked with SUM aggregation function, the highlight of result is correct! Could you please help me to address the issue? If there is an opened bug in AWS Quicksight Q, could you please send a link to track when it is resolved.

Best,
