Intellij, JaCoCo for Kotlin coverage

Question

I use IntelliJ with Kotlin and I use JaCoCo to compute tests coverage. In IntelliJ my code is covered, but I don't see the line covered percentage for my Kotlin classes. I can see it only for Java:

On the other hand my Kotlin classes are covered, my code is green or red. Also when I click on Generate Coverage Report ... in Coverage Window, it generates HTML pages and everything is very well covered.

Could you please tell me why I don't see line covered percentage in my Kotlin classes?
