Constantly there is a problem in 1 Parameter Graph and 2 Parameter Graph. After optimization in the table I see all values of parameters. But on Graphics part of them vanishes.

Whenever there's a problem or error message, your best bet is to check out these resources:

1. Open Issues
2. Errors section
3. FAQ section

In particular, your question is answered by the Open Issues list:

(76499) Exhaustive optimization (2 Parameter Graph) may be unable to plot all values when step is relatively tight compared to the range
A cosmetic/display issue which does not affect the accuracy.

So, tweak your parameter step to not be so tight.

it is not so tight. I try a lot of steps but result was the same.

If you see what you see, the step is too tight for the control to work properly. There are 6 bins between 0 and 2. Unfortunately, there's no interest in fixing this low-impact cosmetic issue at Fidelity so the only reasonable option is to adjust your parameters.

So how many bars I have to leave? 1 or 2? it will give a picture on stability of system?

Considering that I don't know a thing about your strategy's parameters, I can only suggest to experiment.
