Altium Designer Rules problem
The problem was on the stack.

To be exact, on the "Edit Rule Values..." The "Load PCB Layer Stack and calculate track..." was pointing on "Default Stack" and I assigned my pcb document there.
I did the same on the rest rules and problem has been solved.

Although, I see again "Default Stack" as previous I don't see rules being modified recurrently when I choose "Import Change from schematic".
