try properties>dimensions>supress when value is null (it's a check box on right side)

if Country is really an Expression, not a Dimension, check if a check box 'Suppress Zero-Values'  is active (properties->presentation (select Country expression))

if it's a dimension, use Mattsies's way to fix it
