RubyMine rspec individual test files not recognized

Can right click on a directory containing test files and run all specs in the file.

Can not right click on an individual file and run it, it does not recognize that it is a test, can't focus on any individual tests inside the file either. Files have syntax highlighting errors complaining that they can't find "rails_helper" however, running individual tests from the terminal works fine.

Only occurs in a top level rails engine, its sub engines run tests fine.
