What needs to be fixed? I'm no expert by any means, but the way I interpret that page is you can choose only one of the four options. If you choose consistent annual market growth, it ignores any entries for total market, mixed portfolio & random performance. Consistent annual market growth is just a theoretical constant return year in and year out, and the results chart only shows one line as a result - which would make sense in that scenario. I'm not sure how useful that is, but in some cases maybe (shorter periods with actual fixed returns). But I may be all wrong...
You didn't understand my post.
You are correct that you can choose only one of the four options.
And... if you choose
consistent annual market growth, you then enter 1) market growth %, 2) fixed income returns %, and 3) inflation %.
The number that you enter for market growth percentage (default of 10) is completely ignored. This is a bug. It has been discussed here

and in other threads.
Edit to add, I first discovered this while trying to answer this question:
If I select
consistent annual market growth, and supply values for market growth, fixed income returns, and inflation, how does FireCalc know how much of my portfolio is in stocks, and how much is in fixed income?
FireCalc needs to know this because there are separate input parameters for market growth and fixed income returns, and it seems that the tool should apply market growth % to the stock allocation, and fixed income % to the fixed income allocation.
The answer to the question is, "FireCalc does not know how much of your portfolio is stock and how much is fixed income." It ignores the market growth percentage. Broke.
