During flow collector creation the Prometheus section has a checkbox to enable Prometheus that is unselected by default.   The description states:

When `enable` is `true`, the Console plugin queries flow metrics from Prometheus instead of Loki whenever possible.
It is enbaled by default: set it to `false` to disable this feature.

Based on the fact the checkbox is not selected by default, the user gets the impression it is NOT enabled by default.  See screenshot

Also, 'enabled' is misspelled.
