Cubase 5 hidden tracks


I got a problem with my Cubase 5.

Everything had been working fine until a few days ago Cubase loaded differently than previously and asked me about my license - I clicked that my product is already registered. But then when I loaded project something happened. I got some tracks routed to group, but when I solo whole group I can hear more tracks than when I solo each included track that I can see in project view (edit window/mixer window).

Any ideas? I’m about reinstalling whole cubase, but maybe there is better solution?

Thanks for help,

What license do you have, please?
