After I updated to CubeMX Version 6.18.0 (and newer CPU firmware pack 1.13 but this one not related to issue) I opened my older project and migrated to newer version. As a result I got error on Clock Configuration Page (see pic.1).

I saved project and checked if anything changed... I did not hound any changed, but versions (see pics. 2 and 3)

So, I downloaded older version 6.17.0 and there is no such issue. See pic.4 and pic.5 shows RCC block config.
