Intellij IDEA: Why build.sbt is highlighted in red?

Question

After a 2 year pause I resumed work with PlayFramework. So I created a new Play Scala project via Intellij IDEA. But the result was strange:

1. Content of build.sbt is highlighted in red
2. The project contains build.gradle O_o

So the question is: why content of the build.sbt is underlined in red?

That's a known issue which will be fixed shortly. As a work-around, please close the project and re-import it. https://youtrack.jetbrains.com/issue/SCL-13283
