Key Influencer Error..."Failed to Resolve Name 'AI.SAMPLESTRATIFIED'....

[Anonymous]

My colleague and I have a PowerBi report linked to a SQL query that was written in Visual Studio. The query feeding the datset examines sales between this year and last year by department, percent changes between this year and last year, and acategorical variable that says 'sales flat/increasing/decreasing' based on the percent change values. 

When we went to the Key Influencers visual and used the categorical variable in the 'Analyze' section, and tried to add another variable in the 'Explain By', we get an error saying:

"Failed to resolve name 'AI.SAMPLESTRATIFIED'. It is not a valid table, variable, or function name."

This pops up regardless of the variable used. Has anyone else rain into this or a similar error?
