EFB question

hi. I have some questions when doing performance calculations. For example. When selecting computer after completing everything, it doesn’t say which config I have to use, also the clear button doesn’t work. So when I want to try a different configuration to test if the optimum thrust setting changes if y change the parameters it doesn’t. Unless I select manually for example D24 but I don’t think that is the idea of the system. In summary, I can’t clear the calculations and start again and the thrust setting stays the same. Also when selecting g TOGA/FLEX. Which number I have to put so the system recognizes toga and not flex? Thanks!!

The config issue was my mistake. That works fine. But the flex number I think is wrong. Shouldn’t depending on the weight parameters the thrust configuration be a flex and derated? Or de derated configs as D24 will always be assigned manually? Like can that derated configas appear as optimum thrust setting?
