disable automatic sbt link project config sync thingy

i imported an sbt project
there, some directories are configured as "test", meaning there are tests there
src/test/unit/scala/blah....
src/test/integration/scala/blah....

intellij, after importing the sbt project, thinks tests are here
src/java/blah
src/scala/blah

i can change this in the module settings, but after a restart my change is resetted
how can i a) fix it or b) prevent the automatic reset?
