My guess is that the project and its main module aren’t configured properly, e.g., for source roots and such, and that’s why these features aren’t working.
Are you both using the same IDE project files checked into version control, or did you each create your own projects? If the latter, I’d recommend you recreate the project in the same manner as your colleague. Project creation specifics are well-documented in the user guide:
https://bitbucket.org/RoseSilverSoftware/illuminatedcloud/wiki/User_Guide/Home
You can recreate the project in-place by closing it and removing the .idea directory and .iml file (if not under the .idea directory), then reopening the project.
Also note that you can safely check IDE project files into version control to share them:

If recreating the project doesn’t address the issues, feel free to let me know and I’ll be happy to walk you through it.
