This looks like a measure totals problem. Very common. See my post about it here: https://community.powerbi.com/t5/DAX-Commands-and-Tips/Dealing-with-Measure-Totals/td-p/63376

In order to force additivity over your measure you need to aggregate the values using SUMX by iterating the distinct visible values of the column (or column combinations) that represents the core structure of your Table or Matrix visual.

MeasureA Correct Total =
SUMX ( DISTINCT ( 'Table'[Country] ), COALESCE ( [MeasureA], [MeasureB] ) )
