FCP X 10.3 - audio enhancements where have all the settings gone???

So audio enhancements used to have 3 settings: Loudness, fan/hum background noise removal and something I can't remember any more. Where are those?

All I find under Audio Enhancements is Audio Analysis and FIXED. I can’t seem to get into any of the options anymore. It’s as if it was locked down. No permission granted.
So did Apple remove those features?
I’ve used the loudness slider a lot to go OVER the +12 dB FCPX gives me when adjusting waveforms. So what do I do now? Premiere has add audio gain for example and I can add +X dB. I feel like if I have reached the magical 12 in FCPX for audio I am out of luck. Any idea? Thanks.

There is a show/hide button opposite audio analysis





If you're not getting the button it may depend on the clip, where it is, and what its audio configuration is.

Do you know how we can invoke the audio enhancements tabs if they are not available--hide is their but not show. No loudness, etc.

Have some background hum I'd like to remove. Simultaneously having issues with 3rd party plugs causing system crashes so trying to use the native tools but can't access them.

Well, found it again. Not obvious--not adjacent to audio enhancements, but under Equlaizaiton/audio analysis. Seems lame, really.

That said, once invoked, stays invoked, which is nice.
