Changing config on a brand new local cache results in errors

[foundry-markf]

I had a local cache already on disk.
I used the cruiz wizard to register it.
Then I tried enabling revisions and print run commands, and got this error on the console

Traceback (most recent call last):
  File "/Users/mark.final/dev/conan/library_venv310/lib/python3.10/site-packages/cruiz/manage_local_cache/managelocalcachesdialog.py", line 728, in _config_toggle_revisions
    self._config_toggle(checked, ConanConfigBoolean.REVISIONS)

    del self._modifications["Config"][config]
KeyError: 'Config'
