I had a similar conversation via the list on this.

This is the decision of the developers but:

My understanding, which could be wrong, is that DT is not storing the
mix, but the graph of the equalizer. The mix is to reduce or increase
the 'content of the container/pot'. 

* At 0.5 mix, only upper 1/2 of the bottom of the graph is in brown
  (I hope that it makes sense, sorry but English is not my first nor
  second language).
* At 1  the full bottom of the graph is in brown

Apply you preset, then compare the graph with the luma tab, the
chroma tab and the edges tab. Then maybe my explanation will make
sense :)

When you exit the module settings editor, it will adjust the curves based
on the 'mix' value and reset it to 1.0, so the effect is equivalent.

1.000. (see attached). I think the most visible - blue is the edges area.

I am not entirely sure how Equalizer presets should work. I applied 
clarity and set mix at 0.500 and then save it as a preset "test". Next 
time - when I apply the preset "test" - it looks as what I did as a 
correction (the correction applied to the image is correct) - however - 
the mix shows again 1.000. (see attached). I think the most visible - 
blue is the edges area.
