I am not sure if I have understood your question correctly. Do you mean to say that when you add condition for matrix field, you only see one column for calculation?
I did test this issue in my own form and I am unable to replicate the issue you are having. I was able to add the calculation for matrix field. Please check the screenshot below:
I did check your form and found that you have used radio button option. Since only one radio button can be selected per row, that is the reason why you are unable to see rest of the column. If you switch to checkbox option, you should be able to select all columns for calculation. Please check the screenshot below:
Hope this helps.
