The way the "All" conversion work is by matching everything to the hipfire sensitivity of the input game. So when you change the USA coefficient you only change the calculation for the BF4 scopes. Hipfire is the same, so PUBG will also be the same. All the scopes for both games in your screenshots are actually still the same, since the calculator compensates for your change in USA by changing the BF4 scopes.
What you need to do is to make sure the conversion setup matches your BF4 settings. Then calculations will change for PUBG as well.
For your first screenshot the setup should be like this so all your scopes in BF4 are calculated to sensitivity 1:
And if you change either coefficient or zoom all, you also need to change the conversion setup accordingly.
I hope this clears it up!
