IntelliJ Cucumber Test Display in Run window is broken since upgrading Cucumber

Hi,

I hope someone can help with this - I expect it might be something simple.

We're using Java 7 still on a project, but have 8 on compile time (Jenkins), so I have recently updated Cucumber a little (but still quite old) to v2.4.  

(Previously we were on 1.2.4 and this problem didn't exist)

So, this is a feature file for an example:

Basically it shows up in the run window as:

e.g. the scenarios are prefixed by the feature name, and the steps aren't shown.

The only thing that has triggered this is changing Cucumber version - it all worked.

If I add 'pretty' and 'html' output, it displays fine.  This only seems to be affecting IntelliJ?

Can anyone help/advise what might be the cause?

Thanks!
