QSYS Pro 17.0 System Contents window missing or incomplete !!!

Hi to all I'm using Qsys Pro for instantiate some components Ips, I have saved my qsys project but today when I tried to open it The System Contents window is incomplete or it is missing !!! I could see my hierarchy tab with all modules but I couldn't see any interconects on System contents . The qsys project has been corrupted?

I tried to open another qsys project and I saw the same issue

I' m using qsys on a linux machine.
