Studio Console display don't works

Hello. I have upgraded Elements 12 to 13. When trying to open the MixConsole, only the meters are displayed, so it’s impossible to use it…(even after uninstalling Elements 12).

This is a known bug. It transfers wrong Mixer configurations from C12 to 13. This will be addressed with the next maintenance release.

A workaround could be to open C12, configure the Mix console there to show everything, and then reopen the project in C13.
Remember that the C12 project will not contain data about new features only available in C13. If you’re not using new features, it should be no problem, or you can use an empty project.
