Intellij IDEA 2018.1 Jdk10 cannot run test

Question

Cannot run test with IDEA 2018.1 + JDK 10. It says:

Error:(6, 1) java: modules are not supported in -source 8 (use -source 9 or higher to enable modules)

I've raised language level up to 10 using menus:

File->Project Structure -> Project -> Project Language Level 10

File->Project Structure -> Modules{each module} -> Language Level 10

but it didn't help.

What can be reason of the error?
