Trying to edit deco gases can bring up wrong gas

[ltowles@…]

When deco gases are added in an order other that the order they will sort into - ie add 100% first then add 50% - the gasses will sort from lowest o2 to highest as expected but clicking on them to edit them they are still in the order that they where added. So in this example clicking on the 100% to edit it brings up the 50% gas.
