3D oprimization charts not showing anything

I've performed my backtests, and i have lots of results.

Now i would like to view the 3D optimization charts to pick the most stable combination of inputs.

But i click on 3D optimization charts, and i choose my x,y axis parameters, and i tick all the others to stay static.

And i get NOTHING back.

Its strange, because with a similar strategy, i do get something back, but here i get nothing back.

So it seems like these charts needs to pre-requisites to work.
What are they?

Why would nothing come up? like not even the box shows up, i just see an empty white screen
