The problem seems to be what JB2Cool mentioned in the previous thread. You 
have the planner deco pO2 set to 0.60 instead of 1.60. The available gases 
shows both Bot. MOD and Deco switch at. The Bot. MOD uses the Bottom pO2 and 
18m for 50% and 4m for 100% seems fine. The deco switch at uses the Deco pO2 
and in your case it shows nonsense -3m for oxygen. I've recreated your plan 
with Deco pO2 set to 0.60 and 1.60 and the 0.60 matches your values.
