Syntax Highlighting in Scala's import statement (unable to find setting)

Hello,

I am currently using a custom theme, that is showing inconsistent color for import statement in Scala. I tried searching for the relevant section to change to custom color, but I am not able to find one. As per below screenshot it shows grey color which gives an illusion that this import is not used. However I am using it in current scope.

Any suggestions where exactly I can find that configuration?
